Hi,
How to check the health of squid server?
I am thinking about writing a script to connect to squid ip address
with port 3128.
But is that enough?
And what should i expect to receive? Is there some kind of 'ping'
command for squid?
Thank you.
Here's a (very) quick and (very) dirty script* (using wget) that will
verify the server is responding to requests:
++++++++++++++
#!/bin/sh
export http_proxy=http://my.proxy.server:3128/
/usr/bin/wget -q -O /dev/null http://some.url/
if [ $? ] ; then
# Proxy's working.
else
# Proxy's broke.
fi
++++++++++++++
Obviously, this must be run from a client that is allowed proxy access.
As mentioned, Nagios is a much more robust tool for network monitoring.
With Groundwork's Monarch product
(http://sourceforge.net/project/showfiles.php?group_id=130574) it's even
configurable by a mere mortal. Monitoring the performance of your squid
server via Cacti (or some other SNMP query tool) is another good route.

*This script is untested, and does nothing in either case. Verifying
functionality and making it useful is left as an exercise for the reader.
