check_otrs_user.pl

The plugin checks the MySQL database of an OTRS installation. It looks into the tables of session management to count the agent and users.
The return of the scripts includes count of agent, customers and the sum of both.

define command {
command_name check_otrs_user
command_line $USER1$/check_otrsuser.pl -H $HOSTADDRESS$ -U $ARG1$ -P $ARG2$ -w $ARG3$ -c $ARG4$
}

define service {
...
check_command check_otrs_user!nagios!nagios!20!25
...
}

These definition checks through the hosts MySQL database with user nagios and same pass. If eq 20 or more users are logged in the plugin returns a warning. 25 users at the same time will let the script return a critical state.

have a lot of fun...
