Pega 0076 alerts generated even when DSM services aren't enabled
SA-71967
Summary
PEGA0076 alerts are generated on various nodes in response to the nodes that are being (gracefully or otherwise) shutdown. The alert relates to the Decision Strategy Management (DSM) functionality, however, theDSM functionality is not used. This occurs only on a cluster of atleast two nodes.
All the running nodes display PEGA0076 alerts which correspond to other nodes becoming Unavailable (including the case where a node is gracefully shutdown).
Error Messages
PEGA0076 alert displays with a similar message as below:
Node a6def5747454aabb77479975266a of service Aggregation.Default became UNREACHABLE
Steps to Reproduce
Unknown
Root Cause
On a system where DSM functionality was not used explicitly, a default out-of-thebox service was setup (and started on all nodes): DATA-DECISION-SERVICE-AGGREGATION DEFAULT

Resolution
In the event of a graceful shutdown of a node, ignore the PEGA0076 alerts for all other remaining running nodes.
If the alert is unexpected, it is necessary to check the PegaRules.log for the node which is mentioned in the Alert message (in the example above, a6def5747454aabb77479975266a).
