No, they're missing for all the nodes in the cluster. > > I would first check to make sure that every host in the cluster is > reporting the memory usage and network metrics.

They're all reporting back stats if you telnet to 8649: <METRIC NAME="pkts_in" VAL="95695" UNITS="packets" TYPE="ulong" SOURCE="beostat"/> <METRIC NAME="pkts_out" VAL="190432" UNITS="packets" TYPE="ulong" SOURCE="beostat"/> I've stopped gmetad, done an rm -rf on /var/lib/ganglia/rrds/* and then restarted it to force it to recreate it and it only creates the above mentioned RRDs. I've been unable to find where in the config files or the Ganglia code it determines what RRDs get created. I would actually feel better in some ways if it didn't create ANY of them because the problem would likely be much more obvious. ----Steve ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
