Hello,
I am testing deploing ganglia to monitor our servers. I have several
clusters - most of them are small ones, but I do have two large ones -
with over 150 machines to monitor. The issue is that I do not receive
all monitoring data from the machines in large clusters - ganglia-web
...@a2o.si:
Ludmil,
do you have multiple headnodes? Do they receive data from all the
nodes? If yes, did you verify it (telnet to each headnode to port 8649
and count occurences of HOST... xml tag)?

of received metrics. I am still diggin into what the hell is wrong with
ubuntu tcp stack, but alas it is working fine with udp.

So... I got the culprit - it turns out that carbon-cache is slowing down
the whole gmeta daemon
size on the aggregator, to the value
set in the kernel sysctl net.core.rmem_max:
udp_recv_channel { ... buffer = 4194304 }
On the gmetad, I use memcached. It only runs the default 4 threads.
Good luck,
Dave
