Staplr is a trending analysis software. It uses rrdtool to store the data and make the graphs. It is written in PHP and is intended to be run via cron and using the cli php application.
Staplr out of the box currently monitors Apache, lighttpd, memcached, MySQL, pgBouncer, PostgreSQL and SysStat. Staplr was designed to make it very easy to implement new monitors. For more information on writing your own plugin monitors for Staplr, check out the Developer Documentation.
