The round robin database tool (rrdtool) is a system to store and display time-series data (e.g. network bandwidth, machine-room temperature, server load average). it stores the data in round robin databases (rrds), a very compact way that will not expand over time. rrdtool processes the extracted data to enforce a certain data density, allowing for useful graphical representation of data values.

this package contains development files for the lua interfaces to rrds.
