Rrdtool Server Statistics: Since some people have show interest in using Rrdtool that I had mentioned in the previous post, here is a good tutorial and example on how to use it and customize it for your own use. I have written my own scripts to interface into the Round Robin Database and collect and store information. I am using some of the code from the PHP display files mentioned in this tutorial. If you do end up using their code, please find a way to say thank you to the author.
I’ve been using rrd for a while now and love the results.
The best feature and hardest part to understand when setting it up is that the rrd files are a fixed size. You have to understand before hand how often you’ll update the database and what data will go in on each update to create your own rrds. Once it’s setup, it can run for years, and the size of the file won’t change. Makes capacity planning a lot easier if you’r tracking a lot of data.
