Greetings Ganglia Gurus, :)
I recently setup a CentOS 7.2 based cluster and am pulling the ganglia binaries
from the OS distro (ganglia v3.7.2). Things were working well with the base
metrics, so I installed the InfiniBand add-on and see data flowing in from that
as well. So far, so good!
Next I took the example_report.php and updated it with some custom power
metrics that I'm collecting. When I click on the cluster of interest and then
select the my report from the drop down menu, the nodes at the bottom of the
screen work fine and show my metrics, but the aggregated graph just under the
heat map was missing. If I select a raw metric like cpu_user for example I do
see one.
I went through all of the reports in the /usr/share/ganglia/graph.d and none of
them show an aggregate graph. If I would like to present an aggregated graph
is there a configuration option that I need to update, or is my report.php file
just missing something to trigger the aggregate graph? Maybe it is not
supported?
thanks,
brent
