Measuring CPU - need clarification

[aholdt]

Hi All!

I'm new to Zabbix. Have been following the last couple of 1.1 betas, testing out to see if Zabbix can replace our current monitoring system.

For starters I have implemented CPU/memory/disk/number of users tests for all servers in our Citrix farm. Measuring CPU is what puzzles me.

The agent returns a 0.something value (eg. 0.08). I have tried to add a custom multiplier to get % values (Custom Multiplier: 100).

What makes it weird is that I sometimes get values above 100. How can this happen? I use the key: system.cpu.load[,avg5]. The servers are all multiprocessor machines.

It happens on several servers, also older (non hyperthreading) machines.

Regards
Allan

use system.cpu.util instead of system.cpu.load

system.cpu.load[<cpu> <,mode>]: CPU(s) load. Processor load. The cpu and mode are optional. If cpu is missing <b>all</b> is used. If mode is missing <b>avg1</b> is used. Note that this is not percentage.

system.cpu.util[<cpu> <,type> <,mode>]: CPU(s) utilisation. Processor load in percents. The cpu, type and mode are optional. If cpu is missing <b>all</b> is used. If type is missing <b>user</b> is used. If mode is missing <b>avg1</b> is used.</b>

use system.cpu.util instead of system.cpu.load

both of these return ZBX_NOTSUPPORTED when it place cpuo or cpu1 inplace of all.

Any suggestions? There are 2 CPU's in each server.
