RRDTool - Underlying database and graphing engine

RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density.

ServersCheck uses the RRDTool as its underlying database and graphing engine. This tool is shipped by permission of its author with ServersCheck.

As RRDTool is an open format, you can create custom scripts, applications to manage the data beyond the capabilities of ServersCheck. For more information on the RRDTool please visit http://people.ee.ethz.ch/~oetiker/webtools/rrdtool
