Ganglia for MySQL Metrics
I just made some minor updates to the metric collection module I use for monitoring MySQL with Ganglia. It collects over 100 metrics and includes a basic report like:

It works either as a ganglia 3.1-style gmond python module or as a gmetric script, for use with any decent version of ganglia. These are the relevant files:
- the module: mysql.py
- sample module configuration file: mysql.pyconf
- ganglia frontend report: mysql_query_report.php
- dependency module, for parsing InnoDB Status: DBUtil.py
