Installation and Usage

Copy the file apc_info.php to a location accessible to the web server, such as:

www.example.com/apc_info.php

Add the following lines to the munin-node file, usually found in /etc/munin/plugin-conf.d/munin-node.

[php_apc_*]
user root
env.url http://www.example.com/apc_info.php?auto

There are 10 available graphs for this multi graph plugin:

• php_apc_files
• php_apc_fragmentation
• php_apc_hit_miss
• php_apc_purge
• php_apc_rates
• php_apc_usage
• php_apc_mem_size
• php_apc_user_hit_miss
• php_apc_user_entries
• php_apc_user_rates

Each required graph should be added to the plugins directory, usually found in /etc/munin/plugins/.

The common approach is to copy the file apc_php_ to the directory /usr/share/munin/plugins/ and then add a symbolic link to it from /etc/munin/plugins/.

For example:

sudo ln -s /usr/share/munin/plugins/php_apc_ /etc/munin/plugins/php_apc_files
sudo ln -s /usr/share/munin/plugins/php_apc_ /etc/munin/plugins/php_apc_fragmentation
..

After symlinking the files, restart munin-node ($ sudo service munin-node restart).

For more information regarding installation of Munin plugins, read the Munin documentation.
