This plugin is used to monitor website up time and response time.

Error codes will be returned if the website is not responding, the URL does not contain data, does not resolve, or responds slower than specified with the warning and critical input options.

Usage: -w (warning milliseconds) -c (critical milliseconds) -u (url) [ -nocert ]

This script has the following dependencies - netcat, date, wget, echo, awk, tr and cksum.

commands.cfg needs to contain something like the following:

# 'check_website_response' command definition
define command{
command_name check_website_response
command_line $USER1$/ -u $ARG1$ -w $ARG2$ -c $ARG3$

Called with the following command:

check_command check_website_response!""!1000!2000

This script will work on POSIX systems has been tested with the Dash shell in Linux Debian and Nagios core 3.2.1

To use the --no-check-certificate option configure as follows:

command_line $USER1$/ -u $ARG1$ -w $ARG2$ -c $ARG3$ $ARG4$

check_command check_website_response!""!3000!4000!-nocert

I made a few changes since I have a Load Balancer for my 7 webservers and wanted to apply the links to multiple URLs. I added checks but changed service this way:

define service{
host_name web2,web3,web4,web5,web6
check_command check_nrpe!check_website_response_blog

This was it will check the local web server and then on the local web server I added this:

command[check_website_response_blog]=/usr/lib64/nagios/plugins/ -u -w 200 -c 200

Now when a web site goes down it tells me what server its on and that I use "/?web2" to force to use a server instead of letting load balancer decide. Very good tool.

Thank you.

One of those simple things that is simple to add in, and just works.

Had to modify the NETSTAT variable to work with my linux release... trivial.

Exellent, thanks.

Great add-on works well although I cannot get it to work with a non standard HTTP or HTTPS webpage running on TCP port other than 80 or 443.
Does anyone know if its possible to alter part of the code so I can monitor other ports.
Sorry am a bit of a noob so don't know much coding.

This script works fine for us too.
And the patch works fine too and it's compatible with Centreon

This script works very well for us. There's one minor tweak that can make it more useful. This patch will allow you to output performance data that you can log using pnp4nagios.
