A new PATROL Agent is being added for monitoring but it is not created in either TSIM or TSPS
Check the TrueSight.log for messages like the following:
INFO 08/27 09:43:26 PatrolAgentAudit [PatrolAgentAddMsg_3] 600002 Patrol Agent MO already available [11000 14943] for hostname <HOSTNAME> port 3181
ERROR 08/27 09:43:26 Invalid [PatrolAgentAddMsg_3] Exception while creating AgentACKTask for MSG null Missing Resource String
These messages indicate a stale entry for this PATROL Agent exists in the TSIM cache but the actual device has not been created correctly in TSIM.
The output from the TSIM command:
pw device listWill not include the PATROL Agent in question.
At this time the only solution is to restart the TSIM.
This will clear the appropriate cache and allow the PATROL Agent to be successfully created.
