My gmond's always bloat quite large. To combat this, I've dedicated a
single host with massive amount of swap to run a gmonds as a
'collector' role. Every time I add a new cluster, I add a new gmond
instance on the collector box with a new port.
The recent discussion about setting dmax caused me

A good test is to peek at the number of metrics in gmond over time, e.g.

This module is neat, but it's never been a viable module to run in
production in any site I've worked at. I disable it when I detect it
with config management, but if it happens to slip through, cpu on the
host is driven way up with the excessive netstat calls.
Does anybody else notice this?
You choose a single gmond in each cluster as a collector. Gmetad only
polls the collector for each cluster. In unicast mode, you set all
your gmond nodes to send an XDR formatted UDP datagram to the
collectors. In multicast mode, you can choose the collector at random
from gmetad's perspective.
Is there a limit on number of metrics a host can send?
We've got a gmond instance that we've loaded 3700 metrics. When run
in debug mode, gmond reports that it sent with 0 errors, but the
receiving gmond (we're running unicast mode) only shows 224 metrics in
the XML structure when we query it.

You need modpython.conf to include any .pyconf's not gmond.conf
itself. Change the include mysqld.pyconf to:
include ('/etc/ganglia/conf.d/*.conf')
then in /etc/ganglia/conf.d/modpython.conf you should have yet another include:

Hey all, I've cleaned up some of the functions and classes that I've
been reusing while writing various gmond python metrics. I want to
put them in the ganglia_contrib package on github. I forked it and
added my package via submodule -submodule sound ok?
Also, before I add it or do the pull

Obviously, if Ganglia is using up considerable resources, one would want to

Anybody have some tips as to why gmond is converting my float metric

Yeah, thanks. I've been wondering about this functionality too as we
overload our boxes to do very different things. A separate cluster
