# Abstract
|
|
# ~~~~~~~~
|
|
# This is a plugin for the munin monitoring system. It graphs the cache
|
|
# efficiency of your squid proxy servers and shows nice graphs for average
|
|
# byte and request hits.

|
|
# This plugin supports munin-autoconf, but you might need to change the host
|
|
# and port according to your actual setup. You can overwrite the defaults
|
|
# in your node config (/etc/munin/plugin-conf.d/) like this:
|
|
#
|
|
# [squid_efficiency]
|
|
# env.squidhost yourhost.example.com
|
|
# env.squidport 8080
|
|
#
