In case of failover, a clustered check showed "Item not found in monitoring data" instead of fetching the data from the second node. The problem was that the service was discovered on a particular node within the cluster and expected to persist on this node, instead of being fetched from other nodes in the event that a failover had occurred.

This behavior was visible when the rule "Aggregation options for clustered services" was set on "Failover".
