check_load parameters

[stecino]

Can someone decode this for me please?

check_nrpe!check_load -a 15,10,5 30,25,20

I know it's doing a load check for 1sminute, 5th minute and 15th minute

But what are are these arguments mean?

[abrist]

From the plugin's usage:

Usage:check_load [-r] -w WLOAD1,WLOAD5,WLOAD15 -c CLOAD1,CLOAD5,CLOAD15

The first three arguments are the warning threshold for load over 1,5, and15 minutes respectively, and the the last three are the critical thresholds for 1,5, and 15 minutes respectively.

I get that, I just want to know to what threshold level are we checking (numbers, percents)

You are checking the Linux system's load, which pulls from the same three parameters and numeric values you get when you run a TOP this is an average of those values as abrist pointed out above.

I get that, but what combination of 3 numbers is considered as warning for example?

0.70, 0.70.0.70 ??

[abrist]

Any of them will cause an alarm if the threshold is reached. Load is calculated in temporal chunks, each one of the those values (depending on its position) represents load averaged over the respective period of time. So a warning setting of:

Code: Select all

2.0,1.5,1.0

Would warn you *if*:

average load is over 2.0 in the previous minute
average load is over 1.5 in the previous 5 minutes
average load is over 1.0 in the previous 15 minutes

Make sense now?

Got it thanks

Do you have any further questions on this topic?

i have my nrpe.cfg file set like this for check_load..
check_load -w 0.8,0.7,0.6 -c 0.95,0.85,0.8

But I continue to get these alerts...

***** Nagios XI Alert *****

What can I do to set the levels to where I can stop getting alerts/warnings ?
