Hi,
I have restarted all, for sure.
This are the ouputs from the telnet:
node01: http://paste.ubuntu.com/518811/
node02: http://paste.ubuntu.com/518812/
I've done the following to get some output.
on node1 launch:(/usr/sbin/gmond --debug=10 2>&1 ) >
/hpcdrive/homemarc.riera/node01.gmond.debug
this is the complete output:
http://paste.ubuntu.com/518824/
on node02 launch: (/usr/sbin/gmond --debug=10 2>&1 )
> /hpcdrive/homemarc.riera/node02.gmond.debug
this is the complete output:
http://paste.ubuntu.com/518825/
restart gmetad on ganglia server.
Ctrl- C on node01
ctrl-c on node02
I've seen both logs and still don't get whats wrong. shame on me.
Meaningwhile, Ron, another user on the list suggested me to change
something on my gmond.conf
udp_recv_channel {
family = inet4
port = 8649
}
I've tryied, without success. maybe something else should be changed.

Hi
Marc,
on first sight, the configs for node01 and node02 look identical and
correct. Have the "gmonds" on all nodes been restarted after the
changes (just to be sure :-). What do you get from: "telnet node01
8649" and "telnet node02 8649"?
Oh, which version of gmetad/gmond are you running?
Cheers
Martin

[Ganglia-general] gmetad only reads from one node of each data_source
Sorry, I think my response has been discarted because of the
attachments. I send it again with my conf files on pastebin. Sorry to
bother.
My gmond conf has only minor changes. I'm happy to share them .
I link(pastebin) to 3 files, gmond from node01 , node02 and nodegpu01.
node01: http://pastebin.com/wa9mmT3h
node02: http://pastebin.com/ZtwsqnNp
nodegpu01 : http://pastebin.com/3ztHULwd
As I remember, the only changes I had done are name and owner depending
on the Cluster group, and the upd send and recv channel to be different
for each Cluster group.
Thanks.

Hi
Joan,
what you describe sounds fine with regard to "gmetad". "gmetad" will
only talk one node per data_source. If that node fails and you have
more than one node listed, it will [try to] failover to the next
available node. So far, everything is working as expected.
Your problem is that apparently each of node01..10 only "knows" its
own metrics. Nodes listed on the data_source line need to know the
metrics of all nodes in the respective cluster. So it is more a problem
with the configuration of your "gmond" services. Care to share the
configuration of one of the nodes?
Cheers
Martin

[Ganglia-general] gmetad only reads from one node of each data_source
Hello,
I have gmetad with following conf running :
r...@fbmsgga01:/var/lib/ganglia# cat /etc/ganglia/gmetad.conf |grep -v ^# |grep -v ^$
data_source "CPU cluster" node01 node02 node03 node04 node05 node06 node07 node08 node09 node10
data_source "GPU cluster" nodegpu01
gridname "FBM"
r...@fbmsgga01:/var/lib/ganglia#
All nodes and gmetad server are on the same vlan.
I only recieve nodegpu01 and node01 info, but if I stop gmond on node01
I start receiving from node02. If I stop node02 I start receiving from
node03, and so on.
I do not understant what is happening, everithing was working fine
until yesterday, when I restarted gmetad host.
data from nodegpu01 is being received and plotted fine.
What is going on here?
Thanks.
Marc
