After much googling i cannot seem to find the answer, so i hope someone (developer maybe) can help. I was successfully using ganglia 2.5 and 3.0.x. At some point i upgraded to 3.1.x and things went sour. I've even tried to revert back to a known working condition to no avail. So here's my current setup. GMETAD 3.1.4 running under suse 11.1 ppc. Using a basic gmetad.conf file monitoring itself (localhost) for troubleshooting purposes: ---snip from /etc/gmetad.conf --- data_source my cluster localhost gpipnim01 data_source sap_app gpiptcpeap02 ---snip- XML on localhost seems fine. I can telnet to localhost 8469 and get proper results. FWIW : GANGLIA_XML VERSION=3.1.4 SOURCE=gmond RRD's are updating properly in /var/lib/ganglia/rrds/ gmond (on localhost) in debug mode is sending updates (obviously since RRD's are being created). gmond -m shows modules are loaded. Web frontend: When I hit the webpage i get Ganglia cannot find a data source. Is gmond running? When you telnet to 8652 what do you get? Localhost 8649 is the output from gmond on localhost. Localhost 8652 is the interactive port from gmetad which is the port that the web frontend uses to get the metric data.

Ahh yes, i knew there was one other telnet snippet question.

Re: [Ganglia-general] Ganglia cannot find a data source.
Sounds to me like it could be a file permissions problems then. Is your apache server able to access the rrd files and/or port 8652?

Chowning /var/lib/ganglia/rrds to wwwrun didnt yield and changesh. I would think that even if apache didnt have access to the rrd files it would still show other html from the web frontend. How does apache access port 8652? Is there another way to test that? -Ryan On Nov 17, 2009 2:17pm, Brad Nicholes bnicho...@novell.com wrote: Sounds to me like it could be a file permissions problems then.
