The rrd creation values can be found in gmetad/rrd_helpers.c and
gmetad/conf.c

Hi all,
I want to replicate ganglia's storage in Java, using a multicast
listener, storing and manipulating using rrd4j. Firstly has anyone done
anything similar? I'm struggling knowing what parameters to set for the
database and getting an adequate resolution of the metrics captured from
multicast (10-30s for the application I desire). Does anyone know what
the datasource and archive creation commands would be/how many there are?
Secondly, and I think this is the main thing, the capture of information
seems to take ages to be recieved in this way. I'm aware of the MonaLISA
project and their java interfaces into ganglia, but a similar
implementation by myself seems extremely slow. Currently packets seem to
be retrieved at a rate of 1 a second, with each packet containing a
single metric value - I'd like to have a complete set after 10 or so
seconds.Would I be better off sticking to my current method of
interfacing with ganglia's rrd databases directly and extracting content
via the fetch command?
Thanks,
Ian
