I am reporting missing tag scope:notice in
Templates Zabbix server health > Discovery rule High availability cluster node discovery > Trigger prototype Cluster node [

]: Status changed .

I see "scope: notice" on trigger means it not problem, but just something that occured and there is not meaningful "resolution" of that event. So I create two trigger action rules using this concept. One rule that report "Problem" and "Resolved" if no scope:notice tag and separate rule that report "Event" if scope:notice tag exists.

Missing tag than causes confusion when trigger action reports "Cluster node status change was Resolved" for (long forgotten) failover that happened 12h ago which is side-effect of Discard unchanged with heartbeat on zabbix.node.status item.

PS: Discard unchanged with heartbeat also hides failovers when they happen sooner than 12h after previous. Is that intended? I suggest PROBLEM event generation mode Multiple so zabbix reports all failovers properly.
