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.

I wouldn't be so quick to dismiss timeouts as the problem. The 0.9751s it
took to download and parse ganglia's XML tree refers to the time it took the
PHP web frontend to query the gmetad XML whereas the timeout's I was referring
to occur when the gmetad polls

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