I'm trying to stress test gmetad by submitting large numbers of metric updates to a single gmond that gmetad is using as a data_source. When I submit an update to a single metric on a single host and then look at 'rrdtool info' output for the /var/lib/ganglia/rrds/unspecified/hostX/metricY.rrd file, I see a total of 5 changes to that last_update timestamp over a space of 60 seconds or so. When I apply another update to the metric (via gmetric) to gmond the same thing happens. Any ideas as to why the RRD has to be touched five times for every update? Again, this isn't a summary RRD, it's just the RRD recording a single metric on a single host within a cluster. Dave.
