The scenario is a cluster monitored by cdm and cluster probes properly configured.
My intention is to close "alarm A" when "alarm B" is raised. Both of them are asserted to the same Source <cluster_name>.<resource_group_name>.
This is Alarm A:
This is Alarm B:
This would have to be done with a NAS Lua script.
When alarm B came in you would have to check all alarms to see if alarm A existed then close it.
Depending on your environment and number of open alarms this could take some time.
As nas is asynchronous this could cause an issue with processing alarms.
