OK.
I posted a while back that I'd like to have a native ganlia Java
implementation. Your message before says that this is in XDR spec but I
can't find a decent implementation for Java. That and I'm not looking
forward to reading it ;).
I had some time today to hack around with gmetric to see what I could
get working.
I started ethereal with the filter "port 8649" and then ran:
gmetric --name=foo --value=100 --type=uint32
Which produces a packet with the following data:
00000000 00 00 00 00 00 00 00 07 75 69 6e 74 33 32 00 00 |........uint32..|
00000010 00 00 00 04 66 6f 6f 00 00 00 00 04 31 30 30 00 |....foo.....100.|
00000020 00 00 00 01 00 00 00 00 00 00 00 03 00 00 00 3c |...............<|
00000030 00 00 00 00 |....|
00000034
If I replay this packet and change the uint32, foo, and 100 values to custom but use the rest of the data as a
template will I be ok? Seems straight forward enough but I don't want to get bitten by any fun ganglia bugs in my cluster ;)
I was thinking of providing a higher level API do this data and you'd just give it a port and IP to broadcast on and
then the name, value, and type of your gmetric and you'd be good to go...
This way they're would be a java implementation.
