Installation

You need s3curl installed on your machine. Get it from here:
http://developer.amazonwebservices.com/connect/entry.jspa?externalID=128

Setup the .s3curl file for root and note down the ID you used.
Set the ID of your s3 access identifier in 
/etc/munin/plugin-conf.d/munin-node file. 
Also, the plugin needs to run as root so add that, too.
Example: 

[s3_*]
env.s3_id id_name_here
user root

Next, copy the plugin files from the "plugins" folder to your 
munin plugins folder (e.g. /etc/munin/plugins/ ).

Finally, restart the munin-node:

/etc/init.d/munin-node restart

Data should show up 5-10 minutes after that.

Installation
Unfortunately, direct php-cgi execution is not feasible as it uses a seperate
xcache instance and therefore doesn't get the same numbers as the xcache instance 
of the webserver.

Copy the php script (munin_xcache.php) to your webserver. It is protected 
via http authentification, username and password are set in your xcache.ini
file.
Next, set the URL in your /etc/munin/plugin-conf.d/munin-node file:
Example: 

[xcache_*]
env.url http://uname:[email protected]/munin_xcache.php

Next, copy the plugin files from the "plugins" folder to your 
munin plugins folder (e.g. /etc/munin/plugins/ ).

Finally, restart the munin-node:

/etc/init.d/munin-node restart

Data should show up 5-10 minutes after that.
