check_nrpe!check_load!-a '-w 15,10,5 -c 30,20,10'
Can someone give me an explanation on what this is alerting on?
It seems to alert often and we want to raise the numbers, or lower if these are percentages so that the alerts are less frequent.
Thank you

Also on a high load can some body point me in a direction to look for the reason for the high load.
This is an ubuntu box running apache.
Thank you

The Warning and Critical thresholds are checking the load levels for 1 minute, 5 minutes and 15 minutes.
Here is the usage from the plugin
Code: Select all
-w, --warning=WLOAD1,WLOAD5,WLOAD15
Exit with WARNING status if load average exceeds WLOADn
-c, --critical=CLOAD1,CLOAD5,CLOAD15
Exit with CRITICAL status if load average exceed CLOADn
the load average format is the same used by "uptime" and "w"
Here is a link that explains what the load levels mean.

but these numbers are for a percentage? what does the value represent, or what is it measuring?

No, they are not percentages, here is another explanation that I think explains it better:

So if I am getting this,
SERVICE ALERT: cms1;Load;CRITICAL;HARD;5;CRITICAL - load average: 106.01, 51.65, 21.04
Where should I look to find the cause?
Thank you again for the assistance.

Go to the command line and just type in "top" and it'll list everything running and see if something sticks out at you. 100 is a rather high load!
