Yes indeed :) No, RRDTool's cgi is smart enough to only regenerate images when needed. It is configurable, so that if you want it to always generate a fresh graph, you can.

Cricket (which does use rrdtool) caches the graphs.

RE: Mrtg how?
The solution is perhaps not to graph every 5 minutes ... I found a soft based on RRDTool which collect data every 5 minutes but it graphes and generate HTML only when you want (once a hour, or twice) The CPU spent a lot of time making graph with GD, collecting datas take less !

If cricket is not quite right, then there are a heap of other frontends/wrappers for rrd that might fit your purpose. -- -- ABO: finger [EMAIL PROTECTED] for more info, including pgp key --
