I've had ganglia working for a few months, and have now moved it to a dedicated monitoring server at the same time as updating to the latest version.
Unfortunately, during the move, I seem to have lost all the graphs and my log is filling up with: "Unable to write meta data to RRDbs Summary_RRD_update: expected 1 data source readings (got 2) from N:1176:000000:17:..." The data which is viewable on the web pages is updating correctly, so where do I start looking - permissions? nodes? Help... Barry
