Inconsistent CAPC Event forwarding issues from CA Performance Center to Spectrum.

CA Spectrum DX NetOps


A CA Performance Center threshold event was generated and cleared in CAPC but the clear event was only seen in Spectrum. 


Release : 20.2

Component : DX NetOps Spectrum Core / SpectroSERVER


The customer had a redundant CA Performance Center system with the same data source. OneClick was switching between the CA Performance Center server. The following messages were seen in the Spectrum tomcat catalina.out file:

May 05, 2021 14:14:27.061 (PoolThread-6827: GlobalPool => NPCEventManagerWebserviceURLPoller) (NetqosEventLog) - (DEBUG) - Evaluating Event Manager web service location
May 05, 2021 14:14:27.391 (PoolThread-6827: GlobalPool => NPCEventManagerWebserviceURLPoller) (NetqosEventLog) - (DEBUG) - Changing Event Manager URL from http://system1:8281/EventManager/EventManagerWS.asmx to http://system2:8281/EventManager/EventManagerWS.asmx


There were two CAPC systems that had the same OneClick Data Source. OneClick was switching back and forth between the systems causing events to be missed. This is not a supported configuration. The customer disabled the second CAPC system and that resolved the problem.
