Hallo, i'm not able to find the solution to this problem.
If you have a structure with one gmetad that polls another gmetad,
together with the "scalable" option off, for example with the datasource
line in the master gmetad like this:
data_source "abigor-gmetad-server" 50 abigor:8651
when the master gmetad update the data reported by the slave gmetad in
the local archives, the rrdlib return in the syslog a lot of error like
this:
xxx /usr/local/ganglia/sbin/gmetad[27262]: [ID 415359 user.info]
RRD_update
(/usr/local/ganglia/RRDs/cluster_mila/__SummaryInfo__/swap_total.rrd):
illegal
attempt to update using time 1148465547 when last update time is 1148465547
(minimum one second step)
It seems like a double writing of the same data, because the RRDs are
correctly updated anyway..but there's a lot of output to the syslog server.
There'is any workaround to fix this?
I've tried to raise up the polling interval of the master gmetad up to
50 sec., because i've read that the XML returned by gmetad is updated
every 20-30 s, but this has not fix the problem.
