nagios-plugin-http-tao

This is a python plugin for Nagios (written for Nagios 2 originally) that tries to

• be more intelligent: By default, 30x status codes are resolved and only the end result is compared for correctness (unless an endless loop is detected, that is)
• be more configurable: You can specify which status codes are allowed (so you can e.g. allow a 404 as correct, if you just want to check for 5xx or connection errors)

Installation

Put check_http_tao into your plugins directory (e.g. /usr/lib/nagios/plugins.local), and then define some commands:

define command{
        command_name tao_http
        command_line /usr/lib/nagios/plugins.local/check_http_tao $HOSTNAME$
}

# This is a more elaborate example: Connect some HTTP server on a custom port,
# only checking whether the connection works
define command{
        command_name tao_appserver
        command_line /usr/lib/nagios/plugins.local/check_http_tao $HOSTNAME$:8001 404
}
