Hi All, I've just installed ganglia on my small 15 node RHEL3 cluster (mixed ia32 and amd64) and it is basically working well.
There's one small problem though, in that the first time the ganglia web page is opened, one or more of the node graphs are missing and the nodes are marked as 'down'. Clicking on the "Get Fresh Data" button, or changing the displayed metric causes all graphs to appear and they remain visible for the rest of the time the page is displayed. Looking in the /var/log/httpd/error_log shows the following: ERROR: opening '/var/lib/ganglia/rrds/AGG Bioinformatics ASC/comp2-data/load_one.rrd': No such file or directory ERROR: opening '/var/lib/ganglia/rrds/AGG Bioinformatics ASC/dev32.agg.dpi.vic.gov.au/load_one.rrd': No such file or directory ERROR: opening '/var/lib/ganglia/rrds/AGG Bioinformatics ASC/dev64.agg.dpi.vic.gov.au/load_one.rrd': No such file or directory ERROR: opening '/var/lib/ganglia/rrds/AGG Bioinformatics ASC/storage1.agg.dpi.vic.gov.au/load_one.rrd': No such file or directory It doesn't matter which metric is displayed first (and the error log shows the matching .rrd file to be missing), the nodes are always marked 'down', but reapppear when the metric changes or fresh data is forced. There is no real pattern to which nodes will be missing, although there are a couple of 'repeat offenders', which isn't suprising in such a small cluster I guess. It's a minor, but annoying problem. Can anyone point me in the right direction ? Thanks, Andrew
