Hello, can someone help on how to set a Prometheus alert if a specific pod is not in running the state?
basically, this pod that needs to be monitored has a static prefix podname i.e sam-xxxxxxxxx and the suffix will be changed when it gets recreated for some reason. so ideally this needs to be handled by wild card sam-* but it is not working
