Hi Mark,
I assume cnode340 is the head node that all ~340 other gmond's send their data
to. If so, you could reduce the amount of redundant metadata flying around by
increasing send_metadata_interval to 120 seconds or
higher.
That is correct, cnode340 is the head node for ganglia. I have
Well things blew up ~184 hosts. The web interface shows a random number of
hosts down each refresh, although sometimes there are all up. It reports just
~1 second to download and process the XML: Downloading and parsing ganglia's
XML tree took 0.9751s. So I don't think timeouts are the problem.
. In fact even telneting to
the port only lights up Recv-Q for 2 seconds flat.

60 seconds is likely the problem. I would leave it at default ie 15. I can
explain later.

I am using what I think to be a fairly standard gmond.conf:
globals {
daemonize = yes
setuid = yes
user = nobody
debug_level = 0
max_udp_msg_len = 1472
mute = no
deaf = no
allow_extra_data = yes
host_dmax = 86400 /*secs. Expires (removes from web interface) hosts in 1 day
*/
data_source MDACC 60 cnode340:8649
Everything else is default at this point. http://pastebin.com/UAQYxcX3 is a
full copy.

I've got one more idea/concept that I ran into this morning that MIGHT be your
issue, but likely isn't.
RHEL 5 (not sure if 4 does this also) seems to like, upon initial installation,
in the /etc/hosts file, to put the current system name in the line for
localhost.
For instance:
I'll take another shot at this since I didn't get it working last time I posted.
I am running (installed from rpm):
Ganglia Web Frontend version 3.5.2
Ganglia Web Backend (gmetad) version 3.4.0
Gmond version 3.4.0
RHEL 5.5
RPM list:
rpm -qa | grep ganglia
ganglia-gmond-3.4.0-1
Couple comments:
1) Fill in the URL in the cluster section, should be something like
http://cnode340/ganglia
2) In your GMETAD.conf file your data_source should contain the port number:
data_source MDACC 10 cnode340:8649
Note: In previous versions of GMETAD.conf I used 8651 for the data
I found something else.
I remade my RPMS from the source using: rpmbuild -ta --target x86_64
ganglia-3.4.0.tar.gz. Pulled out the originals and re-installed. Copied y old
configs back. Then just to see I ran gmond -m and got an error which ended
the output:
(cut off for brevity, there are no
I am running the following:
Ganglia Web Frontend version 3.5.2
Ganglia Web Backend (gmetad) version 3.4.0
Gmond version 3.4.0
RHEL 5.5
I currently have gmetad and gmond running on a single system (cnode340)
And a single cluster node being monitored (cnode100)
Here are the config files:
Cnode340
to talk just give me stats on itself and will go from there.
