Can anyone suggest what might have happened in the following?
I was trying to pull together a custom metric for ganglia and now, the
machines that it was set up on, their graphical data does not appear on
the Ganglia web pages even though the numerical information is correct.
You can see the problem here:
http://128.100.71.70:81/ganglia/?
c=Yip_Lab_Systems&m=&r=hour&s=descending&hc=4
I restarted the head node that tracks everything, reset the RRDs, etc
and nothing seems to work. If I restart gmond on those affected
machines, you sometimes get a spike on the graph and then nothing -
again, the numerical information is correct, just no trend data...
I've since removed the custom metric but something else is messed up
and I can't figure out where the problem is - i.e. is it on the clients
that are providing the data, or the one that is collecting it..?.. I
did look on the list but the situations that talk about no images refer
to incorrect permissions, or the whole cluster is off - in this case,
it's only selected machines that seemed to be affected...
Thanks
Chris
