Questions tagged [rrdtool]

RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data.

RRDtool (acronym for round-robin database tool) aims to handle time-series data like network bandwidth, temperatures, CPU load, etc. The data are stored in a round-robin database (circular buffer), thus the system storage footprint remains constant over time.

It also includes tools to extract RRD data in a graphical format, for which it was originally intended.

Bindings exist for Perl, Python, Ruby, Tcl, PHP and Lua. And there is an independent full Java implementation, rrd4j.
