check_hastats

The plugin is created with PERL and requires that you know your HAproxy configurations. The check_hastats can read the HAProxy Stats and provide performance output accordingly. First, modify the $specific_line variable by providing the name of the haproxy Web-farm name. (For Example: In the following haproxy.cfg listen section, the tomcatfarm is the Web-farm name)
listen tomcatfarm www.mywebsite.com:80

The plugin reads the haproxy status information in csv format.. You may need to enable a http listener port in order to read HA.Proxy stats..

The Syntax for the plugin is as follows...
check_hastats.pl [servername]:[port] [warn] [critical]

[servername] - The IP address or domain of the HAproxy
[port] - The port number its listening on (works on if enabled)
[warn] - The warning level for the concurrent connections.
[critical] - The critical level for the concurrent connections.

The plugin writes to the /tmp/inha.stats and deletes it soon after. Appreciate your feedback..
