Creating additional plugins for nagios

Team would like to know if anyone here had created a basic nagios plugin.
I did write a simple postfix service checker. Then add it in nagios nrpe.cfg then restart nrpe and nagios and it is not working, its like i cant receive email if the service is stopped or running.

Code:

#!/bin/bash
post=`service postfix status|awk '{print $5}'|tr -d .`
case $post in
running )
echo "the post fix is running"
exit 0
;;
*)
echo "Please check the postfix service"
exit 1
;;
esac

NAME

       Nagios - network/systems status monitoring daemon

SYNOPSIS

       nagios [-h] [-v] [-s] [-d] <main_config_file>

DESCRIPTION

       nagios  is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please
       consult the online documentation available at http://www.nagios.org, or on your nagios server's web page.

OPTIONS

       main_config_file
	      The main configuration file.  On openSUSE systems this defaults to /etc/nagios/nagios.cfg

       -h     A helpful usage message

       -v     Reads all data in the configuration files and performs a basic verification/sanity check.  Always make sure you verify  your  config
	      data before (re)starting Nagios. You can also use the Nagios init script to verify your configuration - try: rcnagios check_verbose

       -s     Shows projected/recommended check scheduling information based on the current data in the configuration files.

       -d     Starts Nagios in daemon mode (instead of as a foreground process).

FILES

       /etc/nagios
	      Default configuration directory for nagios
