It's quite hairy :-). I basically had to turn on E_ERR to figure out some of these errors. I have an apache stacked graph report (modified from Ben Hartshorne) here
http://vuksan.com/linux/ganglia/index.html#Apache_Traffic_Stats I have gotten to a point where I actually have a template that generates these reports. I have also "hacked" things up to give me aggregate stacked and line graphs. I blogged recently about aggregate line graphs http://vuksan.com/blog/2010/06/05/beauty-of-aggregate-line-graphs/ I have been meaning to post bunch of examples but haven't gotten around to it yet. I just uploaded one that aggregates load on all web servers on one graph. You can find it here http://github.com/vvuksan/ganglia-misc/blob/master/graph.d/all_web_load_report.php Hope this helps, Vladimir On Tue, 15 Jun 2010, Art Peck wrote: > Try as I might, and I HAVE tried, I can not seem to get the modular graphs to > work. > > I followed the process here: > https://sourceforge.net/apps/trac/ganglia/wiki/ganglia_modular_graph_documentation > to no avail.
