Nilesh.org Notes on technology and everything else

If you are a networking guy and haven't heard of MRTG[traffic grapher] or RRDtool[a database backend], you should be sitting at home. These are tools used for monitoring traffic loads on network links. There's a good page on MRTG-RRDtool integration. Then there's Cacti which, using RRDtool, can graph almost any data including SNMP. Using Cacti one can do most of the configuration for RRD right from a web interface. Cacti also has 'graph hierarchies', round robin archives and admin management with delegation suitable for colocation situations. I am seriously considering using Cacti for my SNMP capable devices.
