I once needed a way to make sure our Squid proxy cluster operates correctly. So I wrote a rather simple Squid check plugin for the Nagios monitoring software. André Moura has pimped it further. Feel free to use it. It's also available from monitoringexchange.org.

Power of example
Submitted by Anonymous (not verified) on
Your problem is that you give the last parameter wrong. It is "-e 200" not "-e200" (although -h says so).
Example:
check_squid.pl -u http://yahoo.com -p proxy.server.com -l 3128 -e 200
Good luck!
returning (null)
Submitted by Anonymous (not verified) on
Hey there,
thanks for the nice plugin, its definitely helpful.
My Problem is, that if i let Nagios execute the check it always returns (null).
I run it as user nagios manualy and had success:
./check_squid.pl -u http://www.google.com -p srvproxy -l 3128 -o USER -m PASS -e 200
OK - Status: 200 OK
But when i created a service and the command ( i hardcoded everything to eleminate the cause of defect) i just get (null) as result.
define service{
use generic-service ; Name of service template to use
host_name srvproxy
service_description Squid Service
check_command check_squid
}
# 'check_squid' command definition
define command{
command_name check_squid
command_line $USER1$/check_squid.pl -u http://www.google.com -p srvproxy -l 3128 -o USER -m PASS -e 200
}
Is there any known issues ?

In my case , NAGIOS PLUGINS PATH in resource.cfg "/usr/local/nagios/libexec"
and placed check_squid.pl there.
On the other hand USE LIB PATH in check_squid.pl is "/usr/lib/nagios/plugins".
replace USE LIB PATH in check_squid.pl to "/usr/local/nagios/libexec" and restart nagios.
Is it ok?

Hello!
Same thing here, works from a prompt but does nnot work from within nagios.
YES, I already checked the lib path and YES I also have utils.pm in the same directory. Matter of fact I have both utils.pm as well as util.sh in the same directory /usr/local/nagios/libexec.
Hmm, I am lost!
