perf2rrd is a utility written in Java that automates the extraction of performance data from monitoring plugins into round robin database files (.rrd's).

perf2rrd is designed to require very little configuration. Plugins must output perfdata according to the standard, but perf2rrd will do the rest as far as parsing that data, creating RRD files with an appropriate format, and keeping the rrd files up to date.

Performance data can be provided from Icinga via a single file or pipe, or from Icinga 2 from a multiple file spool directory.
