Alerting

Kentik's Alerting page is covered in the following topics:

Notes:
- For a high-level introduction to Kentik's alerting system, see Policy Alerts Overview.
- For a complete list of the portal locations involved in the management and configuration of alerts and mitigations, see Alerting Pages.

The Alerting page lists recent alerts generated by alert policies.
 

About the Alerting Page

The Alerting page lists current and historical alerts generated by Kentik's alerting system, including important information such as the time, severity, and status of alerts, as well as the dimensions and metric values involved in the conditions that triggered each alert. This page also provides access to the Policies Page, where you can manage and configure the policies that generate alerts and determine the system's response to alerts (e.g. notifications and mitigations).

 

Alerting Page UI

The Alerting page provides information about current or recent alerts in your organization. The page includes the following UI elements:

  • Manage Policies: A button that opens the Policies Page (in the same tab).
  • Actions: A button that pops up the Page-wide Actions Menu.
  • Alerting breakdowns: A set of cards with bar charts showing the breakdown of alerts in categories including status, severity, type, and policy (see Alerting Breakdowns). The breakdowns cover the time range selected in the Filters tab (see Alerts List Filters). Hover over any bar in a graph to open a popup with additional information about its alerts.
  • Show/Hide Filters (filter icon): A button that toggles the Filters pane between expanded and collapsed.
  • Group By: A drop-down from which you can choose a property, e.g. status, severity, type, policy, or primary dimension. Alerts that share the same value for that property will be grouped in the table.
  • Search: A field that shows lozenges for the filters currently set in the Filters pane and also enables you to enter text. The Alerts list will be filtered to show only rows that contain the entered text. Click the X at the right of the field to clear entered text, and the X in a lozenge to clear the corresponding filter.
  • Filters Pane: A set of controls that enable you to filter the Alerts list (see Alerts List Filters).
  • Action controls: A set of controls that appear at the top left of the Alerts list and are present only when one or more checkboxes are selected in the Alerts list, enabling you to apply an action to all selected alerts:
    - Action buttons: Buttons that apply the actions detailed in Alert-specific Actions.
    - Selection indicator: Indicates how many alerts are currently selected.
  • Alerts List: A table listing your organization’s alerts (see Alerts List).

Page-wide Actions Menu

The page-wide Actions menu for the Alerting page pops up from the Actions button in the top right corner. This menu includes the following options:

  • Export: Prepares a visual report (PDF) or data table (CSV) to export as described in Portal Export Options. A notification appears at the top of your screen when the report is ready to download.
  • Subscribe: Opens the Subscribe dialog enabling you to create a subscription for your organization’s alerts. The form in the Subscription dialog is the same as on the Subscription tab of the Share dialog (covered in Subscription Tab UI), with the exception of the Share, Selected View, and Lookback fields, which are not included.
  • Unsubscribe: Opens the Unsubscribe dialog. To unsubscribe from a subscription, open the Subscription drop-down, select the one you’d like to unsubscribe from, and click Unsubscribe.
    Note: This option only appears if you are currently subscribed to one or more alert subscriptions.
 

Alerting Breakdowns

The Alerting breakdowns are cards across the top of the page that each display a bar chart representing a different breakdown of alerts. The breakdowns reflect the currently selected Time Range (see Alerts List Filters). Hover over any of the colored bars in a chart for a popup giving the kind and count of the alerts represented by that bar.

Bar charts show the breakdown of different kinds of alerts in various categories.

A breakdown chart is provided for each of the following categories:

  • Status: The bars in the chart each represent alerts with one of the following statuses:
    - Ack Required: The conditions that resulted in the alarm are no longer present, but an acknowledgement is required from a user in your organization before the alert is "cleared” (blue indicator).
    - Alarm: The conditions that resulted in an alarm are ongoing (orange indicator).
    - Cleared: The conditions that resulted in an alarm are no longer present and an acknowledgement, if required, has been provided (green indicator).
  • Severity: The bars in the chart each represent the alerts that were triggered by alert policy thresholds of a given severity level (see General Threshold Settings): Critical (dark purple), Severe (plum), Major (red), Warning (orange), or Minor (yellow).
  • Type: The bars in the chart each represent the different types of alerts: Custom, DDoS, or Query-Based.
  • Policies: The bars in the chart each represent an individual policy that triggered during the selected time range, arranged in descending order from the left based on the number of times each policy triggered. The popup (on hover) gives the name, type, ID, and alert count for the policy.
 

Alerts List Filters

The alerts displayed in the Alerts List can be filtered using the controls in the Filters pane on the left. The pane includes the following filters:

  • Clear all (appears only when you’ve specified one or more filters): A button that removes all currently set filters.
  • Time Range: A control set that filters the listed alerts to specified time range (see Time Range Filter).
  • Status: Checkboxes that filter the alerts to those whose current status matches one of the following:
    - Ack Required: Alerts that are no longer in alarm state but must be manually acknowledged (per alert policy) before being cleared.
    - Alarm: All alerts in an alarm state.
    - Cleared: Alerts that have been cleared.
  • Severity: Checkboxes that filter the alerts to those whose severity matches one of the following: Critical, Severe, Major, Warning, or Minor The severity is determined by the alert policy threshold that triggered the alert.

    - If all checkboxes in the list are checked, clicking this checkbox will deselect all alerts.
  • Select (in alert rows): A checkbox for selecting an individual alert. When you click the box for one or more alerts, an Acknowledge button appears at the top of the Alerts list. If the alert status of any of the selected alerts is Ack Required, clicking this button acknowledges the Ack Required alerts.
    Note: The Acknowledge button is greyed out unless an Ack Required alert is selected.
  • Status: The current status of the alert (see Alert Status).
  • Severity: The severity level (Critical, Severe, Major, Warning, or Minor) of the alert policy threshold that triggered the alert.
  • Type: The type of alert policy: DDoS, Query-based, or Custom (see Policy Types).
  • Policy: The policy name as defined in the alert policy.
  • Policy ID: The policy ID as defined in the alert policy.
  • Tenant: If your system includes tenants (see Tenants in Tenants and Packages) and you’ve enabled Show Tenant Alerts in the Alerts List Filters, your Alerts list will include your tenant’s alarms.
  • Dimensions: The dimensions (see Dimensions Reference) of the key definition, and their values for the keys that caused the alert to enter alarm state (see About Keys). For example, if the key definition is Dest IP, Device (two dimensions) and the key itself (a unique combination of values for the two key dimensions) is 1.10.1.174:s414_ida9_nektie_com then the Dimensions column would show this:
    Dest IP:1.10.1.174
    Device:s414_ida9_nektie_com
    Note: If a dimension value is rendered in blue you can click it to go to its Details page in Core (see Core Details Pages).
  • Metric: The volume of traffic matching the key (see About Keys). The top-X ranking of traffic is performed by evaluating the volume of this matching traffic as measured in the primary metric (see Data Funneling).

  • Alert ID: The system-generated unique ID assigned to the alert when it was triggered. Click the ID to display the alert and its data on the Alert Details Page (opens in new tab).
  • Duration: The length between the alert start time and alert end time.
  • Time: The time (UTC) of the following:
    - The start time of the event that triggered the alarm state.
    - If the event is waiting for an acknowledgement or has been cleared, it shows the end time of the event that triggered the alarm state. Otherwise, the alert is indicated as “Currently Active.”
  • Action: A vertical ellipses at the right of each alert's row, which pops up a menu from which you can apply an action to that alert (see Alert-specific Actions).

Notes:
-
To clear an alarm manually from the Alerts list, see Acknowledge in Alert-specific Actions.
- Alert policies don't generate alerts when in an error state. If you aren’t seeing alerts when you think you should, check the Policy Status on the Alert Policies page (see General Policy Settings).

Note: Depending on your browser settings, details pages may open in a new tab or window.

 
top  |  section

Alert Details Main Display

The main display area of the details page for an alert from a threshold policy is divided into a set of panes, detailed below, that are intended to provide actionable details about the individual alert.

Title Pane

The top-most pane of the page contains the following information:

  • Alert name: The name of this alert, as defined in its policy.
  • Description: A brief summary (if provided in the alert policy) of the specific situation about which this alert is intended to notify users.

Threshold Statistics Pane

This pane shows some or all of the following elements (depending on factors including alert type and the dimensions in the key definition):

  • Dimensions: The names and values of the key dimension(s) — for example, a device and a destination IP address — whose value triggered the alert.
  • Statistics: Statistics that illustrate the situation that generated the alert. Depending on the configuration of the alert policy, these may include information such as baseline flows/s (if the policy uses baselining), actual flows/s, and actual Kpackets/s.
    Note: Each statistic included as described above will be accompanied by a comparison of the actual value to the triggering value defined in the alert policy. For example, if a condition in the policy threshold is "flows/s value is greater than 200% of baseline" then the flows/s statistic will state not only the actual flow/s but also the percent by which the flows/s exceed the baseline flows/s.

Threshold Data Pane

The Data pane shows charts and tables related to the condition that caused the alert. The structure of the Data pane depends on the type of alert:

  • Custom and query-based alerts: The pane includes a time series chart illustrating the traffic (shown in metrics selected in the policy) that caused the alert.
  • DDoS alerts: The pane includes six tabs, each displaying charts and tables showing a different aspect of the traffic covered by the alert (see DDoS Data Tabs).

For all types of alerts, the View in Data Explorer link below each chart takes you to Data Explorer (in the same tab), where the Query sidebar will be set to correspond to the values of the alert’s key. The pane also includes, at the bottom of the page, a Why Was This Triggered? section (on the Insights tab for DDoS alerts), which details the conditions defined in the policy threshold and the actual values for each of those conditions.

DDoS Data Tabs

The Data pane on the Details page of an alert whose type is DDoS will be structured as a set of tabs that each show a different visualization..

The following tabs are included in the Data pane for a DDoS alert:

  • Alert: A time series chart showing the volume of the traffic that triggered the alert based on the volume metrics defined in the policy. Below the chart are two sections that detail why the alert was triggered (which specific conditions were met) and any status changes to the alert.
  • Ingress Interfaces: A time series chart showing traffic volume (in bits/s) on the interfaces where Kentik detected the attack, and a table giving additional detail including the device and site in which the interfaces are located.
  • Traffic Patterns: A time series chart and table help to characterize the nature of the conversations that are driving the traffic volumes causing the alert, including how many sources it has, what services are involved, and whether it's a conversation or unidirectional.
  • Source Countries: A time series chart showing the unique source IPs of attack traffic, and a table ranking the countries from which traffic from those IPs originated.
  • Source Services: A time series chart showing the services that originated the traffic that caused the alert, and a table ranking those services.
  • Packet Size Distribution: A bar chart showing the packets of various sizes in the traffic that triggered the alert, and a table ranking the sizes by volume of traffic.

Note: The time range for the above charts begins 30 minutes before the alert's start time and ends with the current time (if the alert is still in Alarm state) or its end time.

 
top  |  section

Alert Details Page Sidebar

The right-side sidebar provides additional details about the alert.

  • Severity: The alert’s severity level (Critical, Severe, Major, Warning, or Minor). Severity is determined by the alert policy threshold that triggered the alert.
  • Alert Start Time: The start of the period evaluated for the alert.
  • Event End Time: The end of the period evaluated for the alert, minus the counter reset time set on the policy’s Thresholds tab.
  • Alert End Time: The end of the period evaluated for the alert.
  • Status: The state of the alert: Acknowledgement (Ack) Required, Alarm, or Cleared.
  • Alert ID: The Kentik-assigned unique ID for the alert.
  • Mitigation Details: Information about the mitigation automatically triggered by this alert, if any is defined by the alert policy.
  • Policy: The name of the policy by which the alert was triggered (see Alert Policies). The name is a link that takes you to the Edit Policy page for that alert policy (see Policy Settings Pages).
  • Frequency: A summary of the frequency with which this alert has recently occurred. The Show all Occurrences link takes you to the back to the Alerting page, displaying only that policy’s alerts.
  • Dimensions: A set of vertical bar charts, one for each dimension in the key definition, showing how often the same key value was involved in other alerts over the last seven days.
  • Take Action: Buttons that enable additional steps you can take related to the alert:
    - View in Data Explorer: Opens Data Explorer (in a new tab), where the Query sidebar will be set to correspond to the values of the alert’s key. For example, if the dimension in the key definition is Dest IP/CIDR and the value of the key in the alert is 208.76.14.223 then a filter in the Filtering pane will be set to Destination IP/CIDR equals 208.76.14.223.
    - Open Dashboard: Opens (in new tab) the dashboard specified with the Policy Dashboard setting of the alert's policy (see General Policy Settings).
    - Acknowledge (present only when the alert status is Ack Required): Acknowledge the alert, changing the status from Ack Required to Cleared.
    - Debug Alert: Opens the Alert Debug Dialog for this alert.

Notes:
- The details in the sidebar vary between DDoS alerts and non-DDoS alerts.
- For the Details sidebar for NMS alerts, see NMS Alert Details Sidebar.

 

NMS Alert Details Page

The details page for an NMS alert is accessed as described in Alert Details Page Access. While an NMS details page has roughly the same layout as a typical Alert Details Page, there are a few differences, which are covered in the following topics:

 
top  |  section

NMS Alert Details Display

The main display area of the details page for an NMS=based alert is divided into a set of panes, as described in Alert Details Main Display. The topics below cover the content of those panes for an NMS alert.

NMS Statistics Pane

The fields across the top of the page will provide NMS-specific statistics, including the measurement, metric, and dimensions specified on the Dataset tab of the policy that generated the alert.

NMS Data Pane

The Data pane shows charts and tables related to the condition that caused the NMS-based alert. The structure of the Data pane depends on the type of alert:

  • NMS Up/Down: The pane includes an up/down chart that details the status of the alert over time (see Up/Down Visualization).
  • NMS Threshold: The pane includes a line chart detailing the alert’s activity over the time determined by the Lookback drop-down (top right of the chart).

The View in Metrics Explorer link above the chart takes you to Metrics Explorer (in the same tab), where the settings of the Query sidebar will correspond to the values set in the alert’s policy. The pane also includes, at the bottom of the page, a History table, which details alerts that have recently triggered or are currently active.

Up/Down Visualization

This time-based chart type is composed of a series of bars on a horizontal time axis that each represent one segment of the current time range. The color of each bar shows the status of the policy’s data sources (devices, interfaces, or BGP neighbors) at a particular point in time: green = up, red = down, and gray = unknown. Hover over any bar in the chart to open a popup giving the timestamp and the status during that segment.

If an event occurred during a given segment then its bar will be slightly elevated and one of the following icons will appear above the bar:

  • Bell (in a red marker): An alert was triggered.
  • Checkmark (in a green marker): The alert was cleared (according to the policy’s settings).

The visualization also has Lookback drop-down that determines the timeframe covered by the visualization. Options include Alert +/- 1 hr (default), Alert +/- 24 hr, Last 3 hours, Last day, Last 7 days, Last 30 days, and Last 90 days.

Note: For the Alert +/- display options, the graph will display from 1 or 24 hours before the alert was triggered until the current time.
