Web interface caches a lot of the information for example. For example if
you look in
/var/lib/ganglia/conf
there is ganglia_metrics.cache which is PHP serialized array of host to
cluster mappings, host to metrics mappings etc.
Also if you use Nagios integration it will cache a cleaned up ve

If you want to see all clusters in a particular grid you can query gmetad
on port 8651. If you have multiple grids (multiple hosts running gmetad for
different groups of clusters) you will need to query each of those
separately.

Thanks Austin,
That's working but only showing me one cluster, is it a different port for
the other clusters?

Greeting Joseph !!
You can telnet to gmetad service and it will through out the complete XML
output of all the nodes
example # telnet 127.0.0.1 8649

Thanks Vladimir,
Can I build this without proxy? The ganglia site is on my exceptions list:
urllib2.HTTPError: HTTP Error 407: Proxy Authentication Required ( The ISA
Server requires authorization to fulfill the request. Access to the Web
Proxy service is denied. )

You can check check_ganglia_metric written in Python
https://github.com/mconigliaro/check_ganglia_metric
for example how you can parse the XML.
Alternatively, Ganglia Web 3.3.0+ include Nagios integration which does
what you are looking for e.g.
Check multiple metrics on a range of hosts
As far as I'm aware, ganglia outputs its data as XML that the web page then
picks up and processes. What I'm trying to do is write some python that
looks at every node in a cluster group and alerts if any of the metrics are
over a threshold (easy enough) if I can get hold of ganglia's output.
