Sadly, still no resolution. <http://fusion.cs.washington.edu/ganglia/> is supposed to be the top-level web frontend.
It has two data_source lines, pointing to the two clusters: data_source "grAPHics" frame.cs.washington.edu:8651 data_source "Renderfarm" production.cs.washington.edu:8651 One can see the individual cluster graphs at the respective clusters' head nodes: <http://frame.cs.washington.edu/ganglia/> <http://production.cs.washington.edu/ganglia/> However, the top-level (grid-level) statistics only show one of the data sources, there's no "click through to the cluster" available to "drill down" to one of the cluster head nodes, and there are no graphs at the top level. (I thought that perhaps I could add a second cluster to the grid and things would become clearer. Sadly, this was not the case.) Also, on the top-level, the files in /var/lib/ganglia/rrds/__SummaryInfo__ and /var/lib/ganglia/rrds/unspecified/__SummaryInfo__ are the same, and the web front-end is looking for data elsewhere: (from the webserver error_log) ERROR: opening '/var/lib/ganglia/rrds/grAPHics/<nodename>/load_one.rrd': No such file or directory ERROR: opening '/var/lib/ganglia/rrds/grAPHics/__SummaryInfo__/load_one.rrd': No such file or directory Why won't both clusters ('grAPHics' and 'Renderfarm') show up in the toplevel view? I have two data_source lines. How do I change the "Grid" breadcrumb name (just below the Ganglia image in the upper-left corner)? I'm very confused.
