[[File:Rrddemo.png|thumb|RRDtool has a graph function, which presents data from an RRD in a customizable graphical format.]]

'''RRDtool''' (''round-robin database tool'') is a data logging and graphing system for time series data.
It aims to handle [[time series]] data such as [[computer network|network]] [[bandwidth (computing)|bandwidth]], [[temperature]]s or [[Load (computing)|CPU load]]. The data is stored in a [[circular buffer]] based [[database]], thus the system storage footprint remains constant over time.

It also includes tools to extract round-robin data in a graphical format, for which it was originally intended.
Bindings exist for several programming languages, e.g. [[Perl]], [[Python (programming language)|Python]], [[Ruby (programming language)|Ruby]], [[Tcl]], [[PHP]] and [[Lua (programming language)|Lua]]. There is an independent full [[Java (programming language)|Java]] implementation called rrd4j.
