Yup. It would be useful for a number of other things, too. For example, we graph web page load times from Apache, and usually a few pages take much longer than most others. It really does seem like it should be possible to do this, and that rrdgraph already supports it, but I never figured out a way to get logarithmic graphs defined in graph.php Has anyone on this list done it, or even seen it done? -- Cos I originally wrote: > I've defined a lot of custom graphs to view our Ganglia data, because > most of the metrics we want to see are custom metrics.
