This feature enables you to capture up to 5 local environment variables (env vars) at session start on Cmd-enabled servers. The selected env vars are associated with applicable sessions, and appear in the Cmd web app terminal under session details. You must specify each env var you wish to capture.

Note that some SSH configurations permit SSH clients — such as on an employee laptop — to set environment variables in the remote session automatically at session startup. This can be useful, but it is also important to keep in mind for security reasons: env var values may not be under the exclusive control of your server.


This feature is supported for Cmd Control agent versions 1.4.5+ and Cmd Audit agent versions 1.1.0+.


Select env vars to capture

  • Click Specify env variable, and add the name of a variable you wish to capture. Repeat this for any additional variables, up to 5.
    NOTE: Each env var name/key must be < 256 bytes, and each value must be < 4096 bytes. Values longer than 4095 will get truncated to fit into this limit.

Display captured env vars

Captured env vars appear in several places:

  • In the sessions table, you can display a column for each env var. To select which columns appear, click the button on the table's right:
  • In the web app terminal, captured env vars appear both in session entry events (with an expandable button), and in the session details pane:
