So you are now running gmetad on a new box, did you change the host to send in the config files on all the gmond boxes? > Ganglia web shows graphs of historical data until the present time, > for our cluster, but no further: past the point where I moved the RRD > files over, graphs all show blank. > > gmetad is writing new data to RRD files in ganglia/rrds/unspecified > rather than to the existing RRD files in ganglia/rrds/OurCluster > > Why is gmetad doing that?
