Some call it the industry standard data logging and graphing application. Others use it to write their very own full custom monitoring scripts. Most people will probably get in touch with RRDtool through some third party monitoring applications.
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 can create beautiful graphs. It can be used via simple shell scripts or as a perl module.
RRDtool is available for download from this site. Currently it compiles on a number of different Unix platforms as well as on Windows.
