This plugin checks the haproxy.cfg syntax and dead members. It will also issues either a Warning or Critical alert with performance stats of file size change. A Critical Alert will indicate the HaProxy will NOT startup if a "service haproxy restart" was issued by you.
1. Alerts if someone has made a erroneous modification to the syntax.
2. Alerts if a Load-Balanced member is no longer reachable via DNS name (This was beneficial when identifying dead members before restarting HaProxy)
3. Alerts if the haproxy.cfg file size is above a threshold (in bytes).

Performance data output included by default.

# Syntax:
./check_haproxy_config.sh -x -f -c
-x path to the haproxy binary
-f path to the haproxy configuration
-c critical manageable size for your configuration file (in bytes)

# Example Usage:
/usr/local/nagios/libexec/check_haproxy_config.sh -x /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c 8000

# How to use it?
Add the following line to the /usr/local/nagios/etc/nrpe.cfg
command[check_haproxy_config]=/usr/local/nagios/libexec/check_haproxy_config.sh -x $ARG1$ -f $ARG2$ -c $ARG3$

Edit the downloaded plugin and make sure these three lines are accurate.
