I have Ganglia 3.0.1-1 on a 14 node Fedora Core 3 cluster. gmetad and the Apache web server are running on a Redhat 9 admin host.
After a fair bit of playing with the config files, I finally managed to get a cluster report to display, but almost always some of the host metric graphs are displayed as the Mozilla "broken image" icon. Each refresh of the page (e.g. by clicking the "Get Fresh Data" button) creates a different set of broken graphs, so it does not seem to be related to the cluster hosts. The only error message I could find was in the httpd error_log: *** attempt to put segment in horiz list twice But this error is also output when, on the rare occurrence, all the metric graphs are properly displayed. Has anyone seen this error before? My guess is that rrdtool is failing to create the image, but I can't find what is breaking it. Thanks, Marc. -- Marc Langlois <marc at keyseismic dot com>
