Check correct operation of a Squid Web Proxy server

This check command runs a HTTP request through your proxy. You can use it to check the basic proxy operation, authentication and even authentication on a certain web site. You may check for any HTTP error/result code. So this plugin can be useful for checking that certain server do not allow access without authentication, too.

Get the plugin from Nagios Exchange or this site.

  1. Hi, I am try the check_squid.pl

    ./check_squid.pl -u http://www.google.com.gt -p 10.1.15.4 -l 3128 -e 200

    My problem this:

    CRITICAL – Status: 403 Forbidden (but expected 200…)

    What is wrong ?

    • I have no idea, there can be several things. You didn’t specify a user/pass, that might be it if your squid require it.
