Installation and Usage

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

www.example.com/php_opcache.php

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

[php_opcache_*]
user root
env.URL http://www.example.com/php_opcache.php

(the uppercase for URL is important.)

There are 5 available graphs for this multi graph plugin:

• php_opcache_memory
• php_opcache_hitrate
• php_opcache_hits
• php_opcache_misses
• php_opcache_keys

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

The common approach is to copy the file php_opcache_ 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_opcache_ /etc/munin/plugins/php_opcache_memory
sudo ln -s /usr/share/munin/plugins/php_opcache_ /etc/munin/plugins/php_opcache_hitrate
..

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

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