Toney, Have you verified that rrdtool itself works? It may not be a problem with ganglia you're looking at but a problem with rrdtool itself.
I'm not sure what might show up in the apache logs, but that may be a good place to look as well. You should be able to find your rrd databases for ganglia on the node running gmetad (which may be all the nodes). My installation puts them in /var/lib/ganglia/rrds, but I'm not sure if that's the default location. Assuming they are there... bash$ cd /var/lib/ganglia/rrds/__SummaryInfo__/ bash$ rrdtool graph /tmp/foo.png --end now --start end-120000s \ > --width 400 DEF:myline=cpu_nice.rrd:sum:AVERAGE \ > LINE1:myline#0000FF:"foo\n" bash$ file /tmp/foo.png /tmp/foo.png: GIF image data, version 87a, 480 x 155 bash$ xv /tmp/foo.png #or some other way of viewing it If foo.png is a real graph, then you have verified that rrdtool is working correctly. If you cannot get rrdtool to create a graph for you, you should investigate why it is not working correctly before continuing to troubleshoot ganglia. -ben On Mon, Jul 17, 2006 at 12:13:25PM +0530, toney samuel wrote: > Hi, i have specified the path as per your instruction but still i am not > getting and graph in the web page. > > On 7/15/06, matt massie <[EMAIL PROTECTED]> wrote: > > > >toney samuel wrote: > >> Hi i have installed as per the instructions on this link > >> > >> http://www.ibm.com/collaboration/wiki/display/WikiPtype/ ganglia > >> <http://www.ibm.com/collaboration/wiki/display/WikiPtype/ganglia> > >> > >> I am able to get the ganglia page and also the status of my node.
