The mysqlard daemon collects MySQL performance
data in a round robin database using rrdtool.
rrdtool stores the data in a very compact way that
will not expand over time, and it presents useful
graphs by processing the data to enforce a certain
data density. The main goal of the package is to
help the database system administrator in tuning
the system for maximum performance. The package
also contains example graphing, cron, and PHP
scripts.
