I am facing a problem in that I would like short-segment up to date
information from ganglia in order to monitor services after invocation.
Whilst connecting to a port will provide the most immediate metrics, I
would like information over a particular time period. Inspection of
ganglia's round robin databases provides this also, but if most
immediate information is requested - i.e Invoke this service, collect
ganglia metrics for that period, many metric values are left empty
(NaN). I increase the speed at which localhost is polled, but still much
information is to be written to rrd afterwards. A second query sometime
later and these are populated. Is there a way to force gmond writes to
rrd. Or another method to obtain such information from ganglia?
Thanks,
Ian
