Vineet-
I'm kind of new too, but I'll take a stab at this one...

for your data_source line on machine A
you want EITHER, localhost OR the remote system_ip:port
not both.

Machine B is 'broadcasting" on port 8655 at IP 10.0.3.20
so that is where you want the data to come from.

Take a look at that data by telneting to that port (telnet 10.0.3.20 8655) You'll see the xml data scroll by.

(You would use localhost to retrieve the data from you localhost for that port, but you said that you didn't change the multicast port on A, therefore you don't want to use localhost as a data_source on that port. Can you follow all that? <grin>)

I Think I got that right ... <smile>

Hey Guys,

I’ve worked with cacti before, but am new with ganglia.

I went over the mails in the list, but still not clear.

I cannot get graphs from remote machines.

I’ve installed ganglia core on machine ‘A’

Machine A: (gmond and gmetad running)

Default gmetad.conf,

Changed just one line, data_source "my cluster" localhost 10.0.3.20:8655

For this machine

eth0: 192.168.1.50

eth1: 10.0.1.19

Machine B( here gmond is running)

Default gmond.conf, changed multicast port to 8655

For this machine:

Ip = 10.0.3.20

I cannot get graphs of machine B.

Any ideas where things messing up?

Thanks,

vineet
