While there are many graphing tools out there and we’ve used Munin for a while now.
The MySQL plugin for Munin had fallen out of date and the show engine innodb status output changed in 5.5 making some bits of the plugin simply not work any more. Also the show global status has some extra variables so there was a need to create new graphs.
All of these are now in the 2.1.8+ development releases of Munin.
Here are samples of the new/updated graphs.
Some of these above graphs may miss a variable or two with MariaDB-10 because of variable name changes. These will be corrected when we get to those. In MariaDB-10 there is useful transition to information schema tables for status information which will make it significantly easier to parse.
Individual buffer pool information also has been parsed out however we haven’t worked out how to graphing this correctly. Also not yet merged is a bunch of Galera graphs which are currently waiting on some Galera provider changes.
We’ll continue to work with the Munin developers to keep this MySQL plugin up to date and useful.
There’s other graphs in the MySQL Munin plugins that we haven’t changed so aren’t included here.
