Unless you specifically care about single cores maxing out, you probably only want to alert on “Average” (Which is the usage number task manager / top / etc will show you anyway). A 36 core/thread CPU with 1 core at 100% is only 3% used.

Subject: [Observium] Help with Alert Checker again / Multiprocessor System

CAUTION EXTERNAL EMAIL: DO NOT open attachments or click links from unknown or unexpected emails.

Hey List,

after fixing the problem with dont check mountpoints, here´s the next one ...

we´ve a Server with 2 CPU; I defined an Alert Checker

Entity DeviceHostname Match "*" and

Condition "processor_usage gt 95" ...

Now, when I look into my Alert Checkers, I see my Server with Processor "Average" and 2 times "Intel Xeon Processorname ... "

that confuses me a little ... and now the actual Problem:

When Observium send an Alert-Mail, I get 3 Mails ... 1 for "Average" and one for each Processor ... but actually it is enough if I only get one Email ... can I configure this somewhere ?

I helped myself by extend the Entity with "Processor_Description notmatch *average" ... but I don´t know if this is the right way ...

Can somebody help here?

Thanks in advance.

Regards,

Michael
