Nagios plugin for checking Squid
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.

Status: 400 URL must be absolute
Hi,
As you can see I tried many known and unknown URLs, but never received the correct responce. Very odd.

CRITICAL - Status: 406 Not Acceptable (but expected 200...)

Best regards, me
Power of example
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)
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 ?
