Device-specific Dimensions

Dimensions that are unique to a specific data source, e.g. a particular router model, are covered in the following topics:

Notes:
- The categorization of dimensions in the topics below corresponds to the categories by which the dimensions are shown in the Dimension Selector Dialog (part of the ad hoc filter controls in the Filtering Options dialog).
- Except where noted, the dimensions listed in the tables below are available for both filtering and group-by.
- The value type refers to the data type (text, integer, etc.) of the dimension value.
- The column type refers to whether the dimension is literally stored in KDE (native) or derived at query-time from other KDE-stored information (virtual); see KDE Query Efficiency.
- The KDE name(s) given below, which represent the KDE column(s) corresponding to each dimension, may be used in API queries made with the Query SQL Method.
- As indicated by column type, some columns are native (actually stored in the backend) while others are virtual (derived from other information). In general, filtering with dimensions based on native columns will return results faster than filtering with dimensions based on virtual columns.

About Device-specific Dimensions

Device-specific dimensions originate as flow records that are specific to given types of devices, whether physical or virtual, such as Kubernetes containers, Palo Alto Networks firewalls, or Cisco ASA appliances. These records are ingested into Kentik as Universal Data Records (UDR), allowing flexible allocation of flow fields to the columns of the Kentik Data Engine. The resulting dimensions are used for filter or group-by like any other fields in Kentik-ingested flow records.

Notes:
- Kentik also stores and uses certain Device-specific Metrics.
- UDR dimensions have no persistent KDE columns.

Cisco nvzFlow Dimensions

Cisco AnyConnect version 4.2, a Cisco VPN client, introduced support for extended visibility into endpoint network communication. This is achieved with the export of network metadata using the IPFIX protocol called Cisco Network Visibility Flow protocol (nvzFlow). The protocol is designed to provide greater network visibility of endpoints in a lightweight manner. The IPFIX protocol is extended with a small set of high-value endpoint context data. This enables IT administrators to have a better understanding of the following vectors:

  • User: Who is accessing enterprise networks and using applications?
  • Device: Which device is used for access?
  • Client application: Which application is used for access?
  • Location: Which location is access being performed from?
  • Destination application: Which SaaS application has been accessed?

Kentik dimensions for Cisco nvzFlow are described in the table below.

VMware SD-WAN Dimensions

VMware SD-WAN Edge devices (formerly known as Velocloud) support flow export via the IPFIX protocol. The VMware SASE Orchestrator allows users to configure Netflow collectors and filters as network services at the Profile, Edge, and Segment level. Users can configure a maximum of two collectors per Segment and eight collectors per Profile and Edge, with support for a maximum of 16 filters per collector.

An IP flow is typically identified by the five-tuple of source IP, destination IP, source port, destination port, and protocol. In Netflow records exported by SD-WAN Edge, however, flows with different source ports are aggregated if they share the same source and destination IPs and same destination port.
