I have a cluster setup with /etc/gmetad.conf configured to pull XML data out of
two daemons for the same cluster.
Both have their own subset of data (one does system performance and the other
does ipmi metrics) and all seems to work well
except that sometimes gmetad seems to pull the data from both so quickly that
both reports use the same timestamp. That should be OK since the metrics are
not the same (i.e. first the cpu load is recorded, then from the second stream
the cpu temperature is recorded, however it then floods /var/log/messages with
complains that the last update was not at least one second ago.
I was thinking of patching gmetad/rrdhelper.c to log it as a debug message
instead of an error since then it will only end up
in syslog when gmetad was started with debug>0.
Are there other (better) solutions to the issue, short of having to integrate
both XML streams into one?
I see previous postings with the issue but no solution:

The specific versions of ganglia-gmetad and rrdtool are:
ganglia-gmetad-3.0.7
rrdtool-1.0.49
The patch I had in mind was
diff -c gmetad-orig/rrd_helpers.c gmetad/rrd_helpers.c
*** gmetad-orig/rrd_helpers.c 2009-05-01 01:01:33.000000000 -0700
--- gmetad/rrd_helpers.c 2009-05-01 01:01:49.000000000 -0700

pthread_mutex_unlock( &rrd_mutex );
return 0;
