Hi Aaron,
You are correct. In creating the aggregate graph cpu_used for one of the
nodes, node1, did not work. For the others it did. However, the cpu_used
graph works for node1 under the "Main" tab and clicking on that particular
node, node1, under the list of metrics. Similarly, under the "Main" tab,
if chose to display the metric "cpu_used" from the drop down list, it
displays the correct graph for node1. What could be the issue? Is there
a different metric for the aggregate graphs than the what is displayed
under the "Main" tab? If so, how to fix this?

I'm trying to create aggregate graphs under the "Aggregate Graphs" tab in
ganglia web. I am running into an issue where if I use the wild card, " *
", for multiple nodes that start with the same name, it produces just the
bars with no graphs underneath. However, if I write the complete name of
one node, it displays the graphs correctly. Anyone know why it's not
working correctly for multiple nodes? Thanks.
I believe I have observed this in the past when one host doesn't have the
metric indicated - hence an RRD for that host/metric combo is missing. I
don't believe those graphs work correctly if only some of the hosts
matching the regex have the metric being displayed. Try showing each of
the hosts that should match individually to find out which one doesn't
work. Alternatively, maybe the host regex is including a different type of
host which doesn't have an RRD for the metric you are requesting?
