What do you mean exactly by "not responding to Ganglia"??
Are you using unicast or multicast?
Have you tried to tcpdump to see if data is being sent ?
Cheers,

Hello Jared,
yes, most likely this is because of multicasting.
Unless you really want to use multiple gmond as collectors, it's simpler and
more robust to use unicast to the gmond on the host which runs gmetad.
Otherwise, to debug multicast the first thing would be to tcpdump on the host
running

Hello Doug,
I'm not sure if it's the kind of "extract stats" that you have in mind, but you
can simply use rrdtool to dump the rrd files created by Ganglia to an XML
format.
Then you can delete the rrd and start anew.
Cheers,

Hi Cristovao,
that depends on how many metrics and on the rrd creation settings. Sure
150MB looks like a lot. An ls -la may give more hints...
Ciao,

Hello Adrian,
if the host for which you send gmetrics is not a gmond "client", you need to
also spoof a "heartbeat" metric, else the collector will think the host is down

Hello Hector,
that lowercase m stands for the "milli" unit prefix. So 20m is 20millipercent
in this case, or 0.020% . You should just use more your CPUs... ;-)

Hello Bejamin,
yes, of course - clusters are "just" many physical (and/or virtual) machines.

Hello Christophe,
(since we've spoken before) as you know we're also using Ganglia. We've
recently added all HLT nodes to the monitoring, so we're up to 1949 nodes
monitored now by a single server - and on the same server we also run Icinga

Eric,
(for v3.2) look at libmetrics/linux/metrics.c . It uses /proc/net/dev .
Anything in common on the non-reporting nodes? HW? OS version?

That depends: shorter time, shorter gaps but more traffic. Longer time, longer
gaps, less traffic. I use ~2 minutes.
Note also this from a previous thread :

Hi Eric, all,
I had tried this but I was ending up with incomplete *_reports (e.g. missing #
of CPUs, total memory etc.).
Seeing this thread, I've tried again, and realised that I also had to adjust
time_threshold for constant or long lived metrics. Hope this helps others who
may stumble in t

I recently saw another occurrence of it but didn't have
Hello Ganglia users and devels,
I have a deployment of Ganglia 3.2 with two monitoring servers and ~300
clients.
Each server runs gWeb2, a single gmetad (C, not Python) and multiple gmond, on
separate ports, for separating different "clusters"
Mostly because of network constraints, I am using
