processor load vs number of CPUs?

[harri]

Hi folks,

Looking at all the multi-core CPUs and hyper-threading on or off, how can I normalize triggers like Template_Linux:Processor Load to the number of real cores?

I mean on a small mail server with a single core the default trigger value might be OK, but on the next number cruncher with 2 quadcores it might be completely unrealistic. Is this normalization something that should be done by zabbix_agentd?

Any helpful comment would be highly appreciated.

Hi,
you could add an item with the number of cpus (cores) of the system using
system.cpu.num[]
and then use it in the trigger configuration in a way that makes sense to you. For example, the current load should not be more than double the number of cores, or something like that.

cheers,

Stefano
