"mysql_size_ondisk - Munin plugin that reports the size of the files and
|
|
directories in /var/lib/mysql, biggest to smallest.
|
|
To correctly count InnoDB tables you should have innodb_file_per_table enabled
|
|
in MySQL (good practise anyway), otherwise all InnoDB tables will be counted into
|
|
ibdataX.
|
|
This plugin must be run as the user mysql, to do that append the following
|
|
to your /etc/munin/plugins/plugin-conf.d/munin-node:
|
|
|
|
[mysql_size_ondisk]
|
|
user mysql
|
|
|
|
This plugin gives you similar information as mysql_size_all. A difference
|
|
is that mysql_size_ondisk is much faster (0.4 seconds vs 14 seconds, on a server
|
|
with 170 databases, 26 GB total). Also note that mysql_size_all gives you the net
|
|
data size, mysql_size_ondisk gives you the gross storage space used, which may be
|
|
much more than your actual data."
