"cpu load" gives high values while nothing is going on

[frater]

Last weekend we replaced a Pentium 4 Machine running Windows 2003 with a Xeon-machine running Windows SBS 2011 (Windows 2008 R2).

The client is running Zabbix agent 2.0 RC3

More or less the same software is running on it and when I run task manager on that machine there isn't a lot going on, but in the mean time the triggers for 30%, 60% and 80% are constantly going off.

It's the only machine that does this (of the 20 servers I'm monitoring).
It's also the only machine with the brand new Xeon processor and probably the fastest one...

Maybe the code needs adapting?

I've added a screen-shot of the processor load...
The first half of the month is the old Pentium Server which had a heavy job, the brand new Xeon is running smoothly.

The graphs show opposite results.

In the meantime we added another Xeon-server and also that one seems to be running a heavy load under Zabbix. I don't believe that's the case for that server neither....

Would love to know what's going on....
They are running 2.0 clients....
It's not happening on other 2.0 clients

if you monitor the load with native system tools, do they show increased load as well ?
if you stop the zabbix agent, does the load change ?

would be nice to understand whether we suspect agent increasing the load, or some reporting mismatch, or something else

No, it doesn't

No, as I wrote already... there's hardly any load on the machine in reality

what is the key, actually ?
doesn't seem to be load...
run both 1.8 & 2.0 agent, monitor the same thing. are the levels ~ the same ?

I can still make the graph...
load, load5, load15 it gives the same results...
