Suspend Monitoring of Individual Cluster Nodes
Alert suppression windows can be applied to groups, clusters, instances, and machines - including individual cluster nodes. Howerer it seems it is only possible to suspend monitoring for instnaces or clusters not individual nodes,
We recently had a hardware fault and it would have been helpful to suspned monitoring of a specific node whislt the engineer resolved the fault.

Currently, issues with the cluster can make every instance on a server show as down when the cluster has an issue due to the secondary server, even though the server is running fine! We were configuring a new secondary server, with SQL Server not even installed yet. Simply adding that server to the cluster caused all instances to show problems, even though the primary instance was running fine.
