We are using restapi call to generate alert to UIM,and sending them to UMP load balance for high availability purpose. Later we found that some alerts are not clearing even though clear alarm has correct suppression key, then we came to know that the some clear alarms are going through second UMP server, since the robot name is different for both the alerts, the correlation is not happening.
I tried creating a lua script based on NAS AO rule but NAS is not picking these clear alarms.Not sure if NAS is designed to ignore them.
We like to continue with load balancer for wasp. and looking for some ideas,Please provide your suggestions?
Which rest probe is being used?
We are using webservices_restapi alarm calls to generate alarm
webservices_rest calls are made to the ump robot, which in this case is two via the load balancer, which opens the possibility that either sometimes the call is going to one and other times the other ump, or some how the load balancer is doing it.
