    probe_result = probe_helper.run_probe(description, job_cache, probe_credentials)
  File "/opt/SolarWinds/Agent/bin/Plugins/APM/probe_helper.py", line 57, in run_probe
    method = get_probe(description)

Cause

The node applied to the template is using a Linux agent which does not support all of the components that SAM can monitor. See the Linux agent supported components article for more information.

Resolution

  1. Edit the application with the failing component(s).
  2. Expand the Advanced section.
  3. Set the Preferred Polling Method to Agentless.
    Note: You may need to click OVERRIDE TEMPLATE to be able to change this.
  4. Save the changes.
