Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm trying to monitor CPU utilization of windows 7 32bit PC (C2D E8400) using zabbix. I tried both "perf_counter[\Processor Information(_Total)\% Processor Time]" and "system.cpu.util[,system,avg5]". After some time status of these items reverted itself to "Unsupported".

Is this problem on agent side, or at server? How to fix it? Ideally I want to see percentages load per each core.

UPD: topic and description updated.

UPD2: these counters work, but their value are float, and not decimal as I thought.

even the item system.cpu.util[,system,avg5] is possible for linux and windows machines. –  shgnInc Apr 7 at 5:08

CPU load (what you have) is not the same as CPU utilization (what you're trying to get). Load is a measurement of the average number of processes waiting on the processor(s), whilst utilization is the amount of time the processor was doing work during a given time snapshot. You probably want to look at the counter:

perf_counter[\Processor(_Total)\% Processor Time]

It's been a while since I've used zabbix, so syntax might have changed.

yes, you are right, it called utilization –  Konstantin Petrukhnov Jan 5 '11 at 22:56
    
for the record, you can get a list of available perfcounters by issuing something like : typeperf -qx > performance_counters.txt; windows specific parameter syntax can be seen in the zabbix manual at zabbix.com/documentation/1.8/manual/config/… –  Richlv Jan 6 '11 at 13:22

I just added the items and triggers for:

 system.cpu.util[,,avg1]

 system.cpu.util[,,avg5]

 system.cpu.util[,,avg15]

It is working in Zabbix Agent 2.0.4 and Windows 2008. Because have differences between CPU Load and CPU Utilization.
