System information

50 System Analysis and Tuning Guide
Apart form RRDtool's man page (man 1 rrdtool) which gives you only ba-
sic information, you should have a look at the RRDtool home page [http://
oss.oetiker.ch/rrdtool/]. There is a detailed documentation [http://
oss.oetiker.ch/rrdtool/doc/index.en.html] of the rrdtool
command and all its sub-commands. There are also several tutorials [http://
oss.oetiker.ch/rrdtool/tut/index.en.html] to help you understand
the common RRDtool workflow.
If you are interested in monitoring network traffic, have a look at MRTG [http://
oss.oetiker.ch/mrtg/]. It stands for Multi Router Traffic Grapher and can
graph the activity of all sorts of network devices. It can easily make use of RRDtool.
