RRDtool 1.x master build status:test coverage

RRDtool is a little program for easily maintaining a database of time-seriesdata. It comes with a charting program for drawing pretty graphs based onthe data stored.

It is pretty easy to gather status information from all sorts of things,ranging from the temperature in your office to the number of octets whichhave passed through the FDDI interface of your router. But it is not sotrivial to store this data in a efficient and systematic manner. This iswhere RRDtool kicks in. It lets you log and analyze the data you gather fromall kinds of data-sources (DS). The data analysis part of RRDtool is basedon the ability to quickly generate graphical representations of the datavalues collected over a definable time period.
