Unfortunatly, check_load only show the load and not the cpu utilisation, the equivalent of typing
"w" in shell. What I am looking for is more something like "top". See below I have copy
the result of "top".
load = number of tasks in the queue and running (average)
cpu utilisation = % of cpu in use.
Here is the result of top.
--- top ---
09:48:53 up 310 days, 17:31, 1 user, load average: 0.76, 0.51, 0.52
65 processes: 58 sleeping, 7 running, 0 zombie, 0 stopped
CPU0 states: 48.0% user 4.0% system 0.0% nice 0.0% iowait 46.0% idle
CPU1 states: 48.0% user 0.1% system 0.0% nice 0.0% iowait 50.0% idle
You can get this info with
top -b -n 1
Then you can awk, grep or pythonize the output to get whatever you need
However, I do not recommend this method as it is both slow and heavy in
resources usage. Furthermore, those CPU loads are instantaneous values
that represent only 1 second (or any delay top uses to compute those
numbers), and thus can be aberrant regarding what the CPU has during all
the time it was not checked for; i.e. if your check_interval is 5
minutes you should not take a random, 1 second long sample in a 5 min
period but an average value computed over the 5 minutes.
You can get the first line of infos with check_load and check_uptime (contrib)
The second with check_proc
But currently I don't see any way of getter the other lines.
Have a look check_snmp_load.pl and its *netsc *option for the -T
argument (see http://www.manubulon.com/nagios/snmp_load.html)
This might be what you are looking for.
