This will display the current number of messages in queue of a SmarterMail Server.

Client configuration
===================
1) You must have installed SmarterMail Mail Server 5.x or above


Server configuration
====================
1) Put the script files in the appropiate directory on the server. If you compile from source, it should be /usr/local/nagios/libexec.

2) You must have installed PHP 5.2 or above and PHP-SOAP library

3) Be sure you can connect to SmarterMail Webservice client from server

4)  Create command in the configuration file:

define command {
                command_name                   check_queue_sm
                command_line                   $USER1$/check_queue_sm -H=$HOSTADDRESS$ -P=$ARG1$ -p=$ARG2$ -w=$ARG3$ -c=$ARG4$
                }

5) Edit your services configuration and add a check_command directive:

check_command                  check_queue_sm!PORT!PASSWORD!WARNING_VALUE!CRITICAL_VALUE

Example:

check_command                  check_queue_sm!80!password!200!400

* PORT - 80: port where the SmarterMail Webservice is listening
* PASSWORD - password: SmarterMail admin password
* WARNING_VALUE - 200: value when receive a warning alert
* CRITICAL_VALUE - 400: value when receive a critical alert

6) Check and reload configuration:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

/etc/init.d/nagios reload
