Some messages in event logs in windows cluster are copied to every cluster member (or to standby), so if we are monitoring those messages we get trigger alerts for every host in cluster.
The only difference between those messages are field "Computer" showing on which server message was generated.
This will also needs trigger function "logcomputer".
Optional: Ideally this would also need support of

(for using as parameter in function logcomputer) macro which doesn't work in active agent items, but it could be resolved with user macro holding hostname.

Thank you.
