So I changed the Device match in : hostname notequals high-cpu-server

 

I tested it with command yes > /dev/null & on another server and I get a mail ...

 

unfortunately I got now 2 mails, one with exact processor description in Subject Line

and one with -Average- in Subject Line ...

can somebody explain this:

The checker looks like this now:

Check Condition: Require any condition - processor_usage gt 95

Device match: hostname notequals high-cpu-server

Entity match: processor_descr gt 95

 

Is there still something wrong in this rule ?

Regards

hostname ne blah.blah.com
hostname ne foo.blah.com

These are evaluated as "and", so you can put a lot of "not equals" entries in. You could even write a regular expression to cover all those devices.

BTW, if you don't have any filters, just use * in the match box, as using "hostname match *" will actually run a regular expression matching everything, rather than just, matching everything!
