<p class=MsoNormal>Hi all,<br>
I've looked at the documentation, at the mailling lists, and
googled around, and don't explicitly see it so thought i'd try here....<br>
<br>
On our system, I've set up nagios and it's monitoring a few things (http, etc)
just fine. However, one of our applications is giving us grief and
sometimes starts consuming >80% of a cpu (it's a quad-core
machine). So i'd like to set up a monitor to see how often this
happens and to get notified. Looking around, it seems like
'check_procs' with the CPU metric should do what i want. <br>
<br>
However, it doesn't seem to behave quite as I'd expect. If I look
at 'top' on this linux system, for our 'problem' application, i see this (and
it will be constant like this for > 1 hour):<br>
<i><br>
PID USER PR NI VIRT
RES SHR S %CPU %MEM TIME+ COMMAND<br>
20022 ourapp 18 0 1428m 1.0g 13m S <b><span
style='color:red'>104</span></b> 25.7 442:18.39 java</i><br>
<br>
<br>
So when I run this command, I'd expect to see 1 process flagged:<br>
<br>
<i>[root@ours libexec]# ./check_procs -w 10 -c 20 --metric=CPU<br>
CPU OK: 173 processes<br>
</i><br>
<br>
I've tried adding the '-u' flag but made no difference. Is there
something I'm missing if I want to capture and be notified when a process goes
above a certain CPU usuage (ie. 80%)?<br>
Any help or information you could provide would be appreciated.<br>
<br>
Thanks<o:p></o:p></p>
