Ganglia developers,
I am trying to implement Ganglia on a 500+ node cluster. My goal is to use the
grid functionality to have the data split up into several groupings (by
architecture -- it is a non-homogeneous cluster). The issue I am having is
that every one of my nodes is showing up for all data_source definitions. In
other words, the metrics from all ~500 nodes shows up under each data_source
heading even though I have defined distinct cluster names in the
/etc/gmond.conf files.
My config files are provided below for reference.
Thanks for any advice you can provide,
Mike
