6. Do you have a lot of data to collect? 7. Are you having preformance issues on your MRTG system? Note that, if you switch to RRDTool, this is *only* for the data backend. You will still use MRTG to collect the data, and so configuration is just the same - you dont need to lose anything. The main difference is that, when using RRDTool, MRTG will not re-generate the graphs each polling interval. Instead, you use a CGI application to do this on-demand (hence the performance win). Lots more discussion about this is available on the RRDTool website.
