Hi Steve,
Most likely, your problems are caused by disk I/O activity because
gmetad it trying to update tens of thousands of rrd files every 15
seconds. I have switched to using tmpfs and have no problems monitoring
a little over 1,000 nodes with a single gmetad collector node. The

Instead of cluttering the main ganglia program with this, it might be
better to write a separate application that periodically polls a
gmond/gmetad and parses the XML data to look for potential problems.
In my opinion, this is the proper place since it would act more like a
client tool that uses

People are always worried about ganglia's network or load overhead,
writing into the list and honestly I don't understand where this comes
from. Have you measured a lot of overhead caused by ganglia? I did a
quick check last month when a similar question came up and this is what

I believe that with a gmetad polling interval of 5 minutes you will
probably end up seeing a lot of your nodes as dead. See the host_alive
function in the ganglia.php file. The webfrontend will consider a host
alive as long as it last heard from it in the last 4*TMAX seconds and I
believe that

In our experience, ganglia's use of rrdtool to make the metric graphs

You can recompile ganglia and add this configure/make flag:
CFLAGS=-DREMOVE_BOGUS_SPIKES
For more information, see:
https://github.com/ganglia/monitor-core/blob/master/libmetrics/linux/metrics.c#L321
Since this appears to be so common, maybe this should be default or at
least easier to enable
