I am configuring alerts for nodes that are within a group and everything is fine when one of the node goes down and when a node comes back up again, but the message that arrives is as follows:
ALERT: Node is Unknown
in the same way the message of comes back up is:
ALERT: Node is Unknown
I have tried modifying the variables in different ways and I am not getting the desired result. What I need to get to the mail is:
ALERT: Node TEST is Down
Y
RESET: Node TEST is Up.
Node was down for 9 minutes.
Very simple, But it's not working.
I appreciate the help you can give me.
Regards
