Many network devices provide a wide array of counters and gauges, detailing their operational status. Obtaining this information from the devices is fairly simple using SNMP, netflow, or any other data aquisition method.
The problems start when it comes to storing and analyzing this data. RRDtool can help in this area by providing functions for the storage, processing and presentation of time-series numerical data. RRDtool is also the basis for MRTG3, which is currently under development by Oetiger.
In this talk you will learn how RRDtool works and how you can use it to solve your monitoring problems.
About the Presenter
After earning a Masters degree in Electrical Engineering from the Swiss
Federal Institute of Technology in 1994, Oetiker spent most of his
professional life managing Unix systems, first in England, and, since
1995, at the Swiss Federal Institute of Technology in Zurich. Mostly on
his own time he wrote large parts of MRTG, a tool some ISPs seem to like
quite a lot for producing management-friendly graphs of their network
traffic.
