what does load1, load5, load15 represent?

Post by newkid »

in check_load what do they represent? The help is not helping me....maybe I have pre-conceived notions for instance what I am after is that I want to know about %user %sys etc with respect to CPU load....on centos....so would load1=user ?

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

Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
--extra-opts=[section][@file]
Read options from an ini file. See
https://www.nagios-plugins.org/doc/extra-opts.html
for usage and examples.
-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"
-r, --percpu
Divide the load averages by the number of CPUs (when possible)

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

Basically, like the uptime command.

Additionally, here's a good summary of what the numbers mean relative to a *nix system:
