This provides some performance statistics for Moodle 2 using the standard 'munin' tool.
Place the 'moodle_' file in a convenient location but not in your munin plugins folder.
In your plugins folder symlink the 'moodle_' file to a file called moodle_yourdatabase where the 'yourdatabase' part is the name of your Moodle 2 database. The script infers the database name from the filename. If you have multiple Moodle 2 sites you can perform multiple symlinks with different database names.
Example: in Ubuntu, it would be something like
sudo
cd /etc/munin/plugins
ln -s /usr/share/munin/plugins/moodle_ moodle_moodle2
...assumes you placed the file in /usr/share/munin/plugins and your Moodle database is called 'moodle2'.
In your munin-node plugins configuration file (on Ubuntu this is
/etc/munin/plugin-conf.d/munin-node
), create a new section for moodle_ as follows:
[moodle_*]
env.hostname localhost
env.user moodleuser
env.password moodlepass
env.turnitin 1
...substituting the appropriate details for your site. Remember that the database name is extracted from the symlink name (see above). If you don't use turnitin set that to 0.
'''Restart munin-node''' (see local documentation)
You can test as follows...
munin-run moodle_database
(substitute the name you used). This should produce something like...
