When configuring an snmpd profile, there is the "Alarm Source" field which takes variables, and if you type a $ in the field you get this popup:
Are there other variables available besides those listed here?
Release : DX UIM 20.4*/ 23.4.*
Component : SNMPTD PROBE
Yes. In addition to those listed in the GUI, the following are also available:
$NIM_ROBOT_NAME
$NIM_HUB_NAME
These will cause the alarm "Source" and "Hostname" fields to be updated with the robot name or hub name respectively.
