Issue/Introduction

Performance Management discovery ( scheduled and manual ) aborts / fails.

Environment

PM 23.3.10 or older

Cause

DE603029

In the Tenant-Agnostic Data Collector environment,  if a discovery profile didn't specify the SNMP profile to use, the discovery could hang and then be aborted due to an exception thrown from the SNMP profile sort function.

Resolution

• upgrade to 23.3.11 or above

• workaround:

  In the discovery profile, please select the SNMP profiles so that only the tenant specific SNMP profiles can be used for the discovery. 
  This should make the discovery work.
