I used this script from nagios exchange https://exchange.nagios.org/directory/P ... st/details for many years in nagios2. now on a new server with debian 7 and nagios3 the plugin doesn't exit properly and i can't find the problem. the script is running perfectly in cli started a user root and as user nagios too.

Code: Select all

nagios@srvnag:~$ /usr/lib/nagios/plugins/check_esx.pl -H servername.domainname -u username -p password -l cpu
CHECK_ESX.PL OK - cpu usage=5546.00 MHz (34.66%) | cpu_usagemhz=5546.00Mhz;; cpu_usage=34.66%;;

Nagios Log and Debug output:

when i copy & paste the Final output from Debug log to cli it's running.

here my config.

Code: Select all

define command{
        command_name    check_esx
        command_line    $USER1$/check_esx.pl -H $HOSTADDRESS$ -u username -p password $ARG1$ $ARG2$
        }

Code: Select all

define service{
        use                     generic-service
        hostgroup               esx-servers
        service_description     Check ESX CPU
        check_command           check_esx!-l cpu
        }

after i figured out a problem with $ARGn$ parameters with another script in nagios3 i tried to use the same syntax in service definition which fixes the other problem but without luck:

Code: Select all

define service{
        use                     generic-service
        hostgroup               esx-servers
        service_description     Check ESX CPU
        check_command           check_esx!!-l cpu
        }

here you have to give a ! for every $ARG$ in command definition but as i sayed it didn't work.

Does the password have special characters? Can you try wrapping it in ' '?

Posted: **Fri Dec 04, 2015 3:26 am**

yes i have special characters in the password and i tried single quotes before without luck and i have other passwords with the same special characters used by other plugins and they are working fine. i thought the problem is based on the output of the script because there i a | in the output so i changed the

Code: Select all

illegal_macro_output_chars=`~$^&"|'<>

and

Code: Select all

illegal_object_name_chars=`~!$%^&*|'"<>?,()=

in nagios.cfg but this doesn't work too.

i have set the maximum possible debug level but i didn't get a useful error message in the log.

Can you try to define the password in the resource.cfg file and reference that variable in your service check?

Posted: **Fri Dec 04, 2015 4:48 pm**

i tried this without success but i figured out a working solution.
after trying to set the password in resource.cfg without luck it crossed my mind. i never tried to redirect the command into a new bash and that's the way it works. so here is the working command definition

Code: Select all

define command{
        command_name    check_esx
        command_line    /bin/bash | $USER1$/check_esx.pl -H $HOSTADDRESS$ -u $USER3$ -p $USER4$ $ARG1$ $ARG2$
        }

where $USER3$ and $USER4$ is set in recource.cfg. i didn't know that i can define variables myself. I like this very much and will use it. thank you very much for that.
