Performance Management discovery ( scheduled and manual ) aborts / fails.
PM 23.3.10 or older
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.
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.
