Hi, in the Alertmanager GUI → Status section, can you see your alert manager config present there? We need to check if the Config is getting reflected in the Alertmanager. If the Alertmanager configurations is not getting updated then search for alertmanager-monitoring-rancher-monitor-alertmanger secret in the cattle-monitoring-system namespace. You need to delete this secret since it contains the alertmanager data and after deleting this, new config will get applied. Wait for some time and if the config is correct it will be updated.
Tried your steps, easy to follow, and indeed was the wrong config, however after deleting the secret still showed the wrong config, should be a slack and email receivers instead of pagerduty, which we don’t use
In addition the Status appears disabled, I have tried to read few internet article and Suse documentation but this is not really clear about how to proceed for enabling it
