Nagios own command use

[aleksandrs.jurcenko]

i think, i resolved it, with check_by_ssh plugin.
if i run command mannualy all is ok:
./check_by_ssh -H 170.252.34.127 -l dir+dcsc_ldap -E -C '/usr/local/nagios/libexec/check_load -w 1,1,1 -c 3,3,3'

if i put it to .cfg file:

Code: Select all

define command{
        command_name    my_com2
        command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -l dir+dcsc_ldap -E -C '/usr/local/nagios/libexec/check_load -w $ARG1$ -c $ARG2$'
        }

on check_mk view there will be an error:

Internal error:: 255

That appears to be a check_mk UI specific error for sure. Can you see the service status in Nagios Core? Either way I'd probably dispatch that error off to the check_mk forums for the developers there to advise.

check_by_ssh is indeed a better way than to run your command unwrapped by just defining ssh as a check command, so you're a step closer to solving your problem - however I still would encourage NRPE. Checking load on a remote host is absolutely trivial on any system that NRPE can be compiled and run on.
