This article discusses General Dimensions in Kentik.

Note: As of May 1st, 2025, the Query SQL Method has been deprecated and is no longer supported.

About General Dimensions

General dimensions in Kentik are non-flow device metrics (e.g., SNMP or Streaming Telemetry) and aren't specific to a particular device model. The available general dimensions in the Query sidebar in Data Explorer (see Dimension Panes) vary depending on the device category, Router or Host (see Supported Device Types), and the specific device type.

If a dimension isn’t found here:

Notes:

  • Dimensions in this article are available for filtering and group-by, except when noted.

  • The value type indicates the data type (text, integer) of the dimension value.

  • The column type indicates whether the dimension is stored in KDE (native) or derived from other KDE-stored information (virtual) at query-time (see KDE Query Efficiency).

  • The KDE names represent the corresponding KDE columns.

  • Native columns are stored in the backend, while virtual columns are derived at query-time. Filtering with native columns is generally faster.

Network and Traffic Topology

This category of dimensions is used to filter or group-by on information related to devices including interface names and descriptions, port IDs, etc.

Note: The following dimensions are represented differently in the group-by Dimension Selectors (Group By Dimensions and Matrix By Dimensions dialogs) than in filtering (see Dimension Selector Dialog):

  • Device Name is represented as the Device dimension.

  • Interface Name and Description are represented by the Interface dimension.

  • Traffic Orig/Term is represented as two separate dimensions, Traffic Origination and Traffic Termination.

  • Ultimate Exit Interface Name and Description are represented by the Ultimate Exit Interface dimension.

Application Decodes

Dimensions related to "application decodes" are discussed here.

About Application Decodes

Application decodes dimensions are used to filter or group-by based on host-related fields (e.g. HTTP and DNS-related fields) with which Kentik enriches flow records from our software host agent (see About the Universal Agent). Kentik originally allocated this data to a fixed set of KDE columns but later switched to the more efficient approach of storing it in UDR columns (see Universal Data Records). As a result, data from current host agent versions is queried via dimensions that are categorized as "Application Decodes" in the portal UI while data from older versions is queried via dimensions now categorized as "Legacy Application Decodes."

Application Decodes Dimensions

The dimensions in the table below correspond to application decode fields from current host agent versions, which use UDR columns in KDE (see Universal Data Records).
