Installing RRDTool

Big Sister is able to collect performance data, store it in a database and provide you with nice trend graphics. Currently only one database exactly designed for such purposes is supported: Tobi Oetiker's RRDTool. For this feature to work you will have to download and install RRDTool. At the time this manual was written it was not necessary to install the RRDTool perl modules - having the rrdtool command installed in your path was enough. Anyway it is a good idea to install these modules. In the near future they might improve the performance of your server.

RRDTool is available fromhttp://ee-staff.ethz.ch/~oetiker/webtools/rrdtool/
