Kentik Map Overview

The Kentik Map module of the Kentik portal illustrates the relationship between three main aspects of your Hybrid IT network infrastructure:

  • Clouds: The cloud providers you use for compute and/or storage (AWS, Azure, GCP, IBM).
  • Internet: The external sources and destinations of traffic to and from your network, broken down by Origin Network, Next Hop Network, and Provider (see Provider Classification).
  • On Prem: The sites where your data center infrastructure is located (see About Sites).

In the main (top-level) Kentik map, each of the above areas of your network is represented as a grey rectangle, referred to as a "block," in which you can drill down to get further details about the network's structure and traffic. As a network engineer, this enables you to better understand what's happening on your network in real time, to compare current and historical traffic for specific network entities, and to see common adverse conditions without having to run queries.

Kentik Map Views

The views available in the Kentik map represent the structure of your overall network, the components within that structure, and the traffic between those components. These views enable you to quickly drill down into your infrastructure at any level, where you can see information including the following:

  • The existence and volume of traffic between your sites, such as data centers and branch offices (On Prem block), your clouds (Clouds block), and external networks (Internet block).
  • The sites that make up your on-prem infrastructure, including:
    - Weather Map: The location of sites on a zoomable world map, with multiple layers showing information such as links, utilization, and health.
    - Topology: The architecture and individual devices of each site, as well as details about the traffic on the individual network entities or between entities.
  • The health of network entities and of the connections between entities.
  • The cloud providers you use, including region breakdowns for each cloud provider.
  • The top ASNs (origin and next-op) and service providers (transit, peering, or IX) that account for your network's incoming and outgoing traffic.

Kentik Map Health

The Kentik Map includes network health indicators that are based on a real-time Kentik service that watches key metrics that impact the health of network infrastructure elements. We are currently monitoring health via SNMP polling of network device and interface metrics. The metrics are evaluated and compared to expected ranges to determine what is considered "healthy" and what should be drawn to your attention as an issue, either "warning" or "critical." These issues currently fall into the following categories:

  • Site health - Derived from the devices and interfaces in the site.
  • Device health - Derived from the device metrics and interface metrics on this device:
    - Device Availability: Whether metrics are available for this device.
    - Device Metrics: CPU Utilization, Memory Utilization.
  • Interface health - Derived from the interface metrics for this interface:
    - Interface Availability: Whether metrics are available for this interface.
    - Interface Metrics: Input Interface Utilization, Output Interface Utilization.

Notes:
- In order to be evaluated for health your devices must allow SNMP polling from Kentik (see Enabling SNMP Polling), with the polling interval set to Standard (see SNMP Polling Intervals).
- The health status represented by indicators in the Network Map UI is as of the time at which you opened the map.

Kentik Map Prerequisites

Kentik's mapping capability is built on the core features of the Kentik system. To use Kentik maps effectively, you'll first need to ensure that your overall Kentik setup is as complete as possible:

  • Register all devices: Physical devices (e.g. routers and switches) and host agents (e.g. kprobe) must be registered with Kentik in order for us to receive traffic data:
    - To register devices via the Kentik Onboarding wizard, see Device Setup.
    - To register via the portal's device admin UI, choose Settings from the portal nav menu, then on the resulting Admin page click the Add button for the kind of device (router or host) that you'd like to add (see Add a Device).
  • Configure SNMP on all devices: SNMP polling enables Kentik to enrich traffic data (flow records) with data about the interfaces via which traffic is entering, transiting, and leaving your network:
    - To activate SNMP on a device via the Kentik Onboarding wizard, see Device SNMP Setup.
    - To activate SNMP via the portal's device admin UI, enable polling on the device with the device-specific SNMP configs provided in our Device Configs Directory, and also set the device's Device SNMP Settings.
    Note: To take advantage of the health status feature of Kentik maps, set the SNMP polling interval to Standard (see SNMP Polling Intervals).
  • Register all clouds: A cloud export in Kentik represents one or more cloud resources (e.g. VPCs or subnets) used by your network on a given cloud provider (e.g. AWS, GCP, Azure). To gain visibility into those resources you must register them in Kentik (see Cloud Overview).
  • Assign data sources to sites: A site is a specific user-defined physical location (e.g. the address of a data center) to which one or more data sources (devices, hosts, or clouds) may be assigned (see About Sites).
  • Exclude interfaces from the map: Your organization may have interfaces that, to reduce clutter and improve clarity, you don't want to show up on the map. Before running interface classification, you can set an IC rule that excludes these interfaces (see Exclude Interfaces from Map).
  • Run Interface Classification (see Using Interface Classification): Interface Classification assigns a Network Boundary and Connectivity Type value to every interface in the network:
    - Network Boundary: Classifies interfaces as Internal or External, which enables you to see whether the source and destination of the traffic are both fully within your network or if the traffic crossed a network boundary (came from or went to a different AS; see Network Boundary Attribute).
    - Connectivity Type: Classifies interfaces by their role in the overall network (see Connectivity Type Attribute), such as Transit, IX, Paid Peering, Cloud Interconnect, etc. (see Understanding Connectivity Types).
    Note: Links will be drawn between two sites in the On Prem block if the interfaces that connect them are assigned a Connectivity Type of either Backbone or Datacenter Interconnect.

Exclude Interfaces from Map

To exclude one or more interfaces from the Kentik Map:

  1. In Settings » interface Classification, click the Add Rule button to open the Add Rule dialog (see Rule Dialogs UI).
  2. In the rule's IF settings, specify conditions that will match the interfaces that you'd like to exclude from the map.
  3. In the rule's THEN settings:
    - Set the Connectivity Type to Other.
    - By default the Auto switch will be on. If Network Boundary is not shown as Internal, set Auto to off and manually set Network Boundary to Internal.
  4. Click the Add Rule button at the bottom right. The dialog will close and the new rule will appear in the Rules list:
    - The Connectivity Type | Network Boundary indicator in the rule statement will show Other | Internal.
    - Interfaces matching this rule will not appear in the Kentik Map.
 

Kentik Map Page

The Kentik Map page includes the following main UI elements, which are — except as noted — also present on the pages for Topology Views:

  • Breadcrumbs (in the SubNav): An indicator of your current location within the Kentik portal. As you drill down deeper you can click on a breadcrumb to go back to a higher level.
  • Full width (in the SubNav): A toggle button that expands the map to the maximum horizontal space available within the browser window.
  • View Kube (not present on Cloud Topology views): A link to Kentik Kube, a network traffic and performance module for Kubernetes clusters (activated by request to Customer Support).
  • View Logical Map (not present on cloud topology views): A link to the Logical Map, formerly known as the Network Map.
  • Details (in the SubNav): Toggle visibility of the right-side Details drawer, which contains details about the currently selected map element (see Kentik Map Elements). If no element is selected this button is inactive.
  • Filters: A button that opens a popup showing the filters applied to the data displayed on this page:
    - If filters already exist, each will be represented as a card in the popup. You can remove a filter using the red X at the right of its card, or you can modify or add filters by clicking the Edit Filters button.
    Both of the above buttons open a Filtering Options Dialog.
    - If no filters are currently applied you can add a filter by clicking the Edit Filters button.
  • Time range: A control that indicates the current time range of the data displayed on this page and pops up a calendar form enabling you to specify the time range (see Time Range Control).
  • Color by (present only on AWS Topology and Azure Topology views): The traffic volume of the VPCs in an AWS cloud region is represented by color intensity (greater intensity indicates greater volume). This control lets you choose whether the color intensity is based on bits/second inbound, outbound, or total.
  • Health indicator (heart icon): Indicates the number of issues identified by Kentik on your network. Click to open a popup giving a breakdown of different problem types (e.g. high inbound utilization, high outbound utilization, high memory utilization, etc.). Click the View Problems button to go to the Health Problems Page.
  • Gbits/s legend: A horizontal bar showing the bit rate of traffic associated with the colors used for the squares that each represent a network in the Internet block (see Kentik Map Blocks).
  • Map display area: Occupying the page's main display area, this diagram graphically represents your network environment, including network entities and the links between them (see Kentik Map Display).
The Kentik Map shows the on-prem, cloud, and Internet elements that handle your network's traffic.
 

Kentik Map Display

The main parts of the Kentik map display area are covered in the following topics:

 
top  |  section

Kentik Map Elements

A Kentik map diagram is made up of the following main types of parts:

  • Blocks: Gray rectangles that each enclose different buckets of infrastructure (see Kentik Map Blocks).
  • Network Entities: The individual network components that are shown within blocks:
    - Physical entities: The sites and data sources (devices and hosts) in your data centers.
    Note: Physical entities are each marked with a health indicator; see Element Health Indicators.
    - Virtual entities: The Regions, gateways, VPCs and subnets in your clouds.
    - Logical entities: The ASes and service providers to which your network connects to send or receive traffic.
    Note: Click an entity to either open the Details drawer for that entity (see Kentik Map Details) or pop up a menu listing possible Network Element Actions.
  • Links: Lines representing the connections between blocks and between network entities. Each link is made up of two segments that each have an arrow representing the direction of the traffic. When you hover over a link the volume of traffic in each direction is displayed over the corresponding segment. Links are gray by default, but when a given network element is selected in the diagram the links for that element are rendered in blue.
  • Weather Map: Shown on the Kentik Map landing page only, this is the default view for the On Prem block (see Kentik Weather Map).
  • Topology: A variation of the map that shows the internal architecture of a given map element as well as that element's relationship to other sites and clouds in your network and to external networks. Topology Views are accessed via a View Topology button in a Details popup. Topology views are available for the following entities:
    - On Prem: When chosen in the On Prem block on the Kentik Map landing page, this view shows the interconnection of all sites where you have on-premises network resources, and enables you to select individual sites to see their internal topology.
    - Site: Shows the architecture of the data sources in a given site (see Site Topology).
    - Devices: Shows the relationship of the device to other connected devices, and how the device's interfaces connect to other devices (see Device Topology)
    - Cloud provider: Shows the regions within a given provider, as well as the count of each region's active VPCs and instances (AWS, Azure, IBM) or subnets and VMs (GCP).

Note: In the AWS Topology and Azure Topology views, each VPC is represented as an expandable card.

Element Health Indicators

If health status information (see Kentik Map Health) is available for a given map element representing a physical entity (a site, device, or interface) then that element will be marked in topology views to indicate its overall health status:

  • Critical: If one or more metrics are in critical range, the element will be tinted red.
  • Warning: If one or more metrics are out of normal range, but no metrics are in critical range, the element will be tinted orange.
  • Healthy: If all health metrics for an element are within normal ranges, then the element will have no tint but it will be marked with a small green disk.
  • Unknown (gray): If the health status of the element is unknown (e.g. the element is not currently configured to allow SNMP polling by Kentik) the element will neither be tinted nor marked with a disk.

Further detail about the health status of a given element is available in the following locations:

Network Element Actions

Clicking on a network element pops up a menu from which you can choose the following actions:

  • View Topology (not present for logical entities): Takes you to a topology view for the element (see Topology Views).
  • Show Details: Display information about the element in the Details drawer.
  • Show Connections: Draws traffic indicator lines between the selected entities and other blocks. In the case of the AWS map, Show Connections also draws traffic indicator lines between a selected subnet and other subnets and gateways within the selected VPC.
  • Show in AWS Console (only in AWS Topology view): Open the selected element in the AWS console to make configuration changes.
  • Show Path To (AWS subnets only): Displays a line showing the path that traffic will take out of a subnet towards its destination, which could be another subnet, a router in physical infrastructure, or an interconnection element like a Customer gateway. The line includes a moving arrow that shows the direction of traffic. Hovering on the line opens a popup giving the from/to of the path.

Note: In the AWS Topology view, clicking on the following types of AWS Interconnection Elements will directly open the Details drawer (see Kentik Map Details) rather than the actions menu: Direct Connection, Customer Gateway, Direct Connect Gateway, VPN Connection.

Kentik Map Blocks

The following Kentik map blocks each contain different types of network entities:

  • Clouds: A container for cloud providers (AWS, GCP, Azure, IBM Cloud).
  • Internet: A container for external sources and destinations of traffic to and from your network (ASNs and service providers).
  • On Prem: One of the following:
    - Weather Map (default): A zoomable world map showing the location of sites, with separate layers for information such as links, utilization, and health.
    - Topology: A container for sites where your data center infrastructure is located (see About Sites).
  • Site (shown only in site topology map): A container for the devices in an individual Site.
  • Other Sites (shown only in site topology map): A container for your sites other than the site shown in the Site block.
 
top  |  section

Inter-block Traffic Volume

The links between the blocks on your main (top-level) Kentik map are labeled with the traffic volume between blocks. The following traffic is considered when calculating the volume between the various blocks:

  • On-Prem » Internet: Includes all flows that leave your on-prem infrastructure via an interface whose Network Boundary (see Interface Classification Dimensions) is External, except for the following:
    - Flows whose Connectivity Type (see Understanding Connectivity Types) is Cloud Interconnect;
    - Flows whose Traffic Profile (see Network Classification Dimensions) is From Inside to Cloud.
  • Internet » On-Prem: Includes all flows that enter your on-prem infrastructure via an interface whose Network Boundary is External, except for the following:
    - Flows whose Connectivity Type is Cloud Interconnect;
    - Flows whose Traffic Profile is From Cloud to Inside.
  • On-Prem » Cloud: Includes the following traffic that is leaving your on-prem infrastructure:
    - Flows whose Connectivity Type is Cloud Interconnect;
    - Flows whose Traffic Profile is From Inside to Cloud.
  • Cloud » On-Prem: Includes the following traffic that is entering your on-prem infrastructure:
    - Flows whose Connectivity Type is Cloud Interconnect;
    - Flows whose Traffic Profile is From Cloud to Inside.
  • Cloud » Internet: Include all flows leaving any cloud with a Traffic Profile of From Cloud to Outside.
  • Internet » Cloud: Include all flows entering any cloud with a Traffic Profile of From Outside to Cloud.
  • Regions » On Prem: For Azure, GCP, and IBM Clouds, a line will be drawn between the Cloud Regions Block and the On Prem block.
    Note: These lines do not currently display data rates (coming soon).
  • Regions » Other Clouds: Visualizations for Azure, GCP, and IBM Cloud include a line between the selected cloud’s region block and Other Clouds.
    Note: These lines do not currently display data rates (coming soon).
 
top  |  section

Kentik Weather Map

The weather map is the default view of the On Prem block on the Kentik Map landing page. This zoomable world map shows the location of network entities — typically sites (see About Sites) or cloud regions — as well as the links between them. Use the Links settings in the On Prem Controls to set the type of the links.

Weather Map Clustering

By default, the number of entities in a given location on the map determines how the entities are displayed:

  • Clustered marker: A circle with a number inside indicates a clustered marker, which reduces clutter by using a single marker to represent multiple entities that are nearby to one another.
    - If the Health switch is on in the On Prem Controls then the marker's circumference is made up of segments that each indicate the health of one of the represented entities.
    - Entities in a multi-site marker may be close but not at the same physical location. As you zoom further in on the map (either with your scroll wheel or using the zoom buttons; see On Prem Controls), entities in a multi-site marker may split off into their own separate markers.
    - Hover over the marker to open a popup with information about the entities (see Weather Map Popups).
    - If a clustered marker includes one or more sites, you can click it to open a Kentik Map Details drawer about the entities it contains.
  • Individual marker: A circle with a label indicating the name of a site or cloud region. If a marker represents an individual site you can click it to see information about the site in a Details drawer (the details drawer is not available for individual cloud regions).

Note: You can turn clustering on/off in the On Prem Controls.

Weather Map Popups

The Weather Map includes the following types of popups that open upon hover:

  • Links: If the Links switch is on in the On Prem Controls then links will be drawn between the entities shown on the map. Hover over a link to pop up an indicator giving the traffic volume in each direction, expressed in bps and also (if the Utilization switch is on in the On Prem Controls) as a percent of capacity.
  • Entities: If the Clustering switch is on in the On Prem Controls then hovering over a clustered marker opens a popup with the following information:
    - Health: If the Health switch is on in the On Prem Controls then the popup will contain a breakdown of the health status of the clustered entities.
    - Sites: A section listing the names of the clustered entities that are sites.
    - Regions: If the Cloud Regions switch is on in the On Prem Controls then the popup will contain a section listing the names of the clustered entities that are regions.
 
top  |  section

On Prem Controls

The on prem controls, which open from the layers icon in the On Prem block, determine what is rendered in the block's Weather Map and Topology views.

  • Links: Controls how lines are drawn between entities.
    - Traffic Type: Determines which types of connections are rendered (see Traffic Type Options).
    - Draw Connections Using: Determines which traffic is used when rendering links between entities: All Layers, Layer 3, or Layer 2.
  • Cloud Regions: Determines whether cloud regions are rendered.
    - Cloud Backbone Traffic: Turn on/off rendering of links whose traffic is between the regions of a cloud provider.
  • Utilization: Turn on/off coloring of links in the Weather Map based on utilization:
    - If on, links for which capacity information is available will be colored based on the utilization of the link (traffic as a percent of capacity). The utilization associated with each color will be shown in a legend at the bottom of the map.
    - If off, all links will be rendered as blue lines.
    Note: Capacity information isn't available for links between the regions of a cloud provider.
  • Health: If on, the circumference of clustered markers in the Weather Map will be made up of segments that each indicate the health of one of the represented entities. The health status associated with each color will be shown in a legend at the bottom of the map.
  • Clustering: Reduce clutter on the Weather Map by using a single marker to represent multiple entities that are nearby to one another (see Weather Map Clustering).

Traffic Type Options

The Traffic Type settings enable you to choose how the system draws lines between sites in the On Prem block:

  • Connected Interfaces: Sites will be connected based on the interfaces at different sites that are configured with IP addresses inside of the same subnet. For example, interface 1 in site A with IP address 192.168.1.2 will be connected to interface 2 in site B configured with an IP address of 192.168.1.3. You can choose whether the connections are based on all layers (default), Layer 2 only, or Layer3 only.
  • Site IP: Sites will be connected by running traffic queries from each site’s configured IP range to every other configured Site IP range. The results of the queries are used determine the traffic volume between sites. Connections are drawn as arrow links.
  • Ultimate Exit: Sites will be connected by running traffic queries using Kentik’s BGP Ultimate Exit feature. Each site connected to another site represents a volume of traffic ingressing a source site and egressing the ultimate exit site.

Route Table Details

This pane includes indicators and controls related to route tables on a VPC or transit gateway. The pane's title bar includes the following :

  • Expand/Collapse: Toggles visibility between the title bar only and the full pane.
  • State indicators: Two lozenges that indicate the current state of the routes in the tables:
    - Active: A healthy route with a good destination.
    - Blackholed: A route that is programmed in a table but that can’t be exercised because the destination has disappeared.
  • Open in modal (diagonal arrows icon): Opens the pane in a modal.

The main body of the pane is made up of one or more expandable/collapsible tables. The table name and the state of its routes is shown in a header row, below which each individual row represents a route. The tables each include the following columns:

  • State: Active (green checkmark) or blackholed (red exclamation point).
  • Destination: The destination CIDR block against which traffic is evaluated to determine the route target to which it should be forwarded.
  • Route target: Content depends on whether the Details pane is for a VPC or a transit gateway:
    - VPC: The ID of the gateway that will handle the different routing functions within a VPC.
    - Transit gateway: The Attachment (the transit gateway extension that "lives" in a VPC) and the Next Hop Resource (the next resource that the traffic will enter).

Notes:
- Subnets can either use a main route table (indicated by "Main" in parentheses after the table's name in the header row) or a dedicated route table.
- For additional information on route tables in AWS, see AWS docs on VPC Route Tables.

Topology Views

Kentik Map topology views are covered in the following topics:

Note: The topology view for AWS is distinct from that of other cloud providers.

 
top  |  section

About Topology Views

Topology views provide a picture of the relationships between sites, devices, and interfaces in your on prem infrastructure, as well as the cloud resources in each of your cloud providers. Topology views are available for the following entities:

  • Site: Shows the architecture of the data sources in a given site (see Site Topology).
  • Devices: Shows the relationship of the device to other connected devices, and how the device's interfaces connect to other devices (see Device Topology).
  • Cloud provider: Shows the regions within a given provider, as well as the count of each region's active VPCs and instances (AWS, Azure) or subnets and VMs (GCP).

The UI elements of topology views are similar to those of the main Kentik map, which are covered in Kentik Map Page.

 
top  |  section

Site Architecture

To provide a meaningful on-prem topology view for sites and devices, Kentik relies on user-provided information about the architecture of a site, which is defined in the Edit Site dialog. To define a site's architecture:

  1. From the main Kentik Map, click on a site to open the site's Details drawer.
  2. Click the View Topology button, which will take you to the site's topology view.
  3. Assuming that the site architecture hasn't already been defined, the block for the site will show a number of devices under the heading Unassigned, beneath which is a Configure Site link. Click the link, which will open the Edit Site dialog.
  4. In the Type section (below the address field), click the button that most closely corresponds to your overall concept of how the site is organized (e.g. Data Center, Cloud, etc.).
  5. In the Architecture section, click the Edit Architecture button, which will open the Edit Architecture dialog.
  6. The dialog contains multiple tabs, each of which provides modifiable templates for different "typical" architectures. Click on the template that seems closest to your situation (or choose Custom from the Other tab), which will open the Architecture Edit UI for that template.
  7. Use the architecture edit UI to assign devices to the layers and to rename each layer as needed, then click the Save Architecture button to save your changes.

Architecture Edit UI

The edit UI for site architecture enables you to customize a site architecture template to the specifics of your site. The dialog includes the following UI elements:

  • Close (X at the upper right): Click to close the dialog without saving any changes to the architecture.
  • Layers: A box representing a layer in the architecture and containing the fields described in Layer Fields.
  • Add Layer: Click to add a box for a new layer at a level that's in between two existing layers.
  • Add Parallel Layer: Click to add a box for a new layer that at the same level as an existing layer.
  • Cancel: Click to close the dialog without saving any changes to the architecture.
  • Save Architecture: Click to save all changes to the architecture and close the dialog.

Layer Fields

Each layer of the architecture is represented as a box containing the following fields:

  • Layer: Specify the name of the layer.
  • Devices: Click in the field to choose one or more devices for the layer from a drop-down list of the Kentik-registered devices that have been assigned to this site.
  • Handle: Enables you to drag layers into a different order.
  • Remove (trash icon): Remove this layer from the architecture.
 
top  |  section

Site Topology

Once the architecture has been specified for a site (see Site Architecture) the site's layers and the relationship between the site's devices are rendered in the site's topology view. To access site topology, click the View Site Topology button in the Details drawer for the site (see Details Panes).

Site Topology Blocks

The topology view includes the following blocks (see Kentik Map Blocks):

  • Site: Shows the site as a block like the On Prem block in the standard Kentik Map view (see Site Block).
  • Other Sites: Shows all other sites from your infrastructure.
  • Clouds: Shows your cloud providers (AWS, GCP, Azure, and IBM).
  • Internet: Shows external sources and destinations of traffic to and from your network (ASNs and service providers).

Site Block

The site block is structured according to the layers defined in the site architecture:

  • A labeled icon is shown for each device in the layer to which the device is assigned:
    - Click the icon to open a device Details drawer for that device (see Kentik Map Details).
    - Click the View Device Topology button in the drawer to go to the Device Topology.
  • A line shows the links between connected devices. Hover over a device to highlight all of its links.
  • An Unassigned section shows the devices that haven't yet been assigned to a layer. Click the Configure Site link to assign these devices (see Site Architecture).
 
top  |  section

Device Topology

The device topology view is organized into the following blocks:

  • Upstream Connected Devices: Shows the devices in the same site that are connected to this device and assigned to a higher layer.
  • Parallel Connected Devices: Shows the devices in the same site that are connected to this device and assigned to the same layer.
  • Device: Shows information about the device (see Device Block Information) and its interfaces (see Device Block Interfaces). Click the device name to link to the Network Explorer details page for this device.
  • Downstream Connected Devices: Shows the devices in the same site that are connected to this device and assigned to a lower layer.

Device Block Information

The left side of the device block provides the following general information related to the main device of the topology view:

  • Status: The health of this device (see Element Health Indicators).
  • IP Address: The IP from which this device sends flow to Kentik.
  • Site: The site where the device is located (click to link to the Network Explorer details page for this site).
  • Sample rate: The rate at which the device is sampling flow (see Flow Sampling).
  • Machine Type: The type of the device (e.g. router, host, etc.).
  • Device ID: The device's Kentik-assigned ID.
  • Metrics: Device metrics gathered via SNMP (see Device Metrics Information).

Device Metrics Information

The Metrics section of the device block includes the following information, gathered via SNMP, and controls:

  • View Details: Pops up a view with charts detailing device metrics.
  • CPU Utilization: A chart of CPU utilization on this device during the last 24 hours, plus the highest value during that period.
  • Memory Utilization: A chart of memory utilization on this device during the last 24 hours, plus the highest value during that period.

Device Block Interfaces

The main area of the device block gives the total number of known interfaces on the device and provides a breakdown of those interfaces based on the layer of the devices to which those interfaces connect:

  • Upstream Connected Interfaces: Shows the interfaces connected to a device at a higher layer.
  • Parallel Connected Interfaces: Shows the interfaces connected to a device at the same layer.
  • Unknown Connected Interfaces: Shows interfaces that fall into one of the following categories:
    - The interface is connected to something that's not monitored by Kentik.
    - The interface is a physical member of a logical bundle (multiple physical interfaces defined as a single logical interface).
    - The interface is connected to a Layer 2 device.
  • Downstream Connected Interfaces: Shows the interfaces connected to a device at a lower layer.

Cloud Topology

The topology view is very similar at all levels from cloud provider level down to subnet. The view is organized into the blocks described in the topics below.

Notes:
- Cloud topology for AWS resources is covered in AWS Topology.
- Cloud topology for Azure resources is covered in Azure Topology.

Common Cloud Topology Blocks

The following blocks appear in cloud topology views at all levels:

  • On Prem: Represents your on-premises infrastructure that is connected to the resources in this cloud provider.
  • Other Clouds: Shows the other cloud providers your organization has registered with Kentik, and a link representing traffic (if any) between this cloud provider and the others.
  • Internet: Shows the external sources and destinations of traffic to and from your network (origin networks, service providers, and next-hop networks).

Level-specific Topology Blocks

The following blocks appear in cloud topology views only at the indicated levels:

  • Regions (cloud provider level only): Shows the regions, each represented as a box, where you have resources within this cloud provider. Each box gives the number of VPCs and subnets within that region. To drill down further, click the box for a region and choose View Topology from the popup.
  • VPC (region level in IBM only): Shows the VPCs, each represented as a box, within the region. Each box gives the number of subnets and VMs within that VPC. To drill down further, click the box for a VPC and choose View Topology from the popup.
  • Subnets (region level in GCP; VPC level in IBM): Shows a box for each of your subnets within the VPC or region. For traffic data, click the box and choose Show Details from the popup.
 
top  |  section

AWS Topology

The AWS topology view is organized into the following blocks:

  • On Prem: Represents your on-premises infrastructure that is connected to the resources in this cloud provider.
  • Internet: Shows the external sources and destinations of traffic to and from your network (origin networks, service providers, and next-hop networks).
  • Regions (cloud provider level only): Shows the regions, each represented as a block, where you have resources within this cloud provider.
    - Each region block shows the VPCs in that region. VPCs are expanded (see VPCs below) unless there are more than nine rows of VPCs at the current browser window width, in which case the VPCs are collapsed.
    - Each region block shows the Transit Gateway via which traffic enters and exits.
    - Lines are drawn to and from each region on the map to denote inter-region traffic volumes.
  • VPCs: Click on an individual VPC to expand it to show its component subnets and the VPC connections (see AWS Interconnection Elements) for that VPC. The display of VPCs in a given region block depends on whether the block is expanded or collapsed (see Regions above):
    - Expanded: Each VPC is represented as a labeled card showing VPC name, ID, and configured CIDR block.
    - Collapsed: Each VPC is represented as a square. The color intensity of the square depends on the Color by control (see Kentik Map Page). Hover over the square to see the name, ID, and CIDR.
  • Subnets: The subnets of a VPC are each represented as a card giving the subnet name and IP /CIDR. The subnets are grouped into Availability Zones which are represented by the dashed outlines around each subnet. An AZ represents a physically isolated datacenter in Amazon’s ecosystem. For traffic data about a given subnet, click the subnet and choose Show Details to open the Details drawer.
  • Connections: AWS supports multiple types of connections for entities within AWS as well as between AWS and on premises infrastructure (see AWS Interconnection Elements).

AWS Interconnection Elements

The AWS topology view includes the following interconnection elements:

  • Customer Gateway: Terminates one or more site-to-site VPN connections that are extended from virtual gateways in VPCs.
  • Link Aggregation Group: A logical interface that uses the Link Aggregation Control Protocol (LACP) to aggregate multiple connections at a single AWS Direct Connect endpoint, allowing all connections in the group to be configured and managed a single connection (see Link aggregation groups in AWS docs.
  • Direct connection: Shows the entry/exit point for traffic to/from the On Prem block that transits an AWS Direct Connect circuit. Kentik can visualize AWS Direct Connects whose virtual interfaces extend from a given VPC directly through to an on-prem router or those connected to Transit Gateway routing devices.
  • Direct Connect Gateway: Aggregates one or more direct connect circuits and allows for easy connectivity between VPCs and multiple on-prem connections (see AWS Direct Connect docs).
  • VPN Connection: Connect your Amazon VPC to remote networks and users (see AWS VPN connections docs).
  • VPC connection: When a VPC is expanded its connection gateways (which enable instances in subnets to talk to other instances in other regions, VPCs, and subnets) are shown as labeled squares across the bottom of the VPC block. Currently supported types include internet gateway, peering connection, virtual gateway, TGW attachment, NAT gateway, VPC endpoint interface, and transit gateway.
  • Transit Gateway: An AWS managed high availability and scalability regional network transit hub used to interconnect VPCs and customer networks (see AWS Transit Gateway docs).

The lines drawn between the above interconnection types show the links over which traffic travels to and from entities both within AWS and beyond (e.g. on prem). Most such links are drawn by default, but for the following VPC connection types links are drawn only when Show Connections is chosen from the drop-down Network Element Actions menu: Internet, NAT Gateway, and Virtual Gateway.

 
top  |  section

Azure Topology

The Azure topology view is organized into the following blocks:

  • On Prem: Represents your on-premises infrastructure that is connected to the resources in this cloud provider.
  • Internet: Shows the external sources and destinations of traffic to and from your network (origin networks, service providers, and next-hop networks).
  • Regions: Shows the regions, each represented as a block, where you have resources within this cloud provider. Each region block shows the VNets in that region. Click the Show Details link to open the region's Details drawer (see Kentik Map Details).
  • VNets: The VNets in each region are shown within the region block. By default all VNets in a region are collapsed. Click on an individual VNet to expand it to show its component subnets. The display of the VNets depends on whether any of the VNets are currently expanded:
    - Collapsed: Each VNet is represented as a rectangle showing the VNet's name, ResourceId, and CIDR.
    - Expanded: The expanded VNet is represented as a blue block within which are shown the VNet's subnets and interconnection elements (gateways, etc.), as well as a Show Details link. The remaining VNets are represented as labeled cards showing VNet name, ResourceId, and configured CIDR block.
  • Subnets: The subnets of a VNet are each represented as a rectangle giving the subnet name and IP/CIDR. Click the subnet to open its Details drawer.
  • VNet connections: Azure supports multiple interconnection types (see Azure Interconnection Elements). When a VNet is expanded its interconnections are shown as labeled rectangles across the bottom of the VNet block.

Notes:
- For an overview of Azure networks, see Azure networking services overview.
- For information about Azure virtual networks (VNets) see Microsoft documentation at What is Azure Virtual Network.

A region, showing VNets and interconnection elements, in an Azure topology view.

Azure Interconnection Elements

The Azure topology view includes the following interconnection elements:

  • VNet Gateway: A virtual network gateway is composed of two or more VMs that are automatically configured and deployed to a specific subnet you create called the gateway subnet. The gateway VMs contain routing tables and run specific gateway services. You can't directly configure the VMs that are part of the virtual network gateway, although the settings that you select when configuring your gateway impact the gateway VMs that are created. See Microsoft documentation at What is a virtual network gateway.
  • VNet Peering: Virtual network peering connects two or more VNets. The VNets appear as one for connectivity purposes. The traffic between virtual machines in peered virtual networks uses the Microsoft backbone infrastructure. Like traffic between virtual machines in the same network, traffic is routed through Microsoft's private network only. See Microsoft documentation at Virtual network peering.
  • NAT Gateway: A fully managed Network Address Translation (NAT) service that simplifies outbound Internet connectivity for virtual networks. When configured on a subnet, all outbound connectivity uses the Virtual Network NAT's static public IP addresses. See Microsoft documentation at What is Virtual Network NAT.

Note: For a comparison of Azure peering and gateway options, see Microsoft documentation at VNet peering and VPN gateways.

 

Security Groups & NACLs

The Security Groups & Network ACLs dialog, which opens from the Security Groups & Network ACLs details pane in an AWS topology view (see Security Groups & NACLs Details), provides information related to flows that were denied as a result of a security rule. The dialog contains two tabs, one for security groups and the other for NACLs.

Security Groups Tab

The Security Groups tab contains the following UI elements:

  • Security Groups: A drop-down selector from which to choose a security group.
  • Security group information: A set of fields giving the name, description, account ID, security group ID, and VPC ID of the selected security group.
  • Denied Flows: A table listing flows that were denied by the rules of this security group:
    - The table gives the direction, resource, protocol, port/range, IP version, and description for each listed flow.
    - The flows can be grouped by direction, protocol, or IP version.
    - You can enter text in the filter field to show only rows in which the contents of a column matches the entered text.
    - A View in Data Explorer button at the right of each row will take you to Data Explorer, where the query settings will be set to show the flow.

Network ACLs Tab

The Network ACLs tab contains the following UI elements:

  • Network ACLs: A drop-down selector from which to choose a security group.
  • Network ACL information: A set of fields giving the account ID, and VPC ID of the selected network ACL.
  • Denied Flows: A table listing flows that were denied by the rules of this network ACL:
    - The table gives the direction, rule action, rule number, resource, protocol, port/range, and IP version for each listed flow.
    - The flows can be grouped by direction, protocol, IP version, or rule action.
    - You can enter text in the filter field to show only rows in which the contents of a column matches the entered text.
    - A View in Data Explorer button at the right of each row will take you to Data Explorer, where the query settings will be set to show the flow.
