Question about Event Filters from multiple Event Types

[Thomas Stüfe]

Hi,

one JMC question:

One feature I use very often in JMC is building graphs on the fly from my
event filters. This means I can expose any metric from the JVM and see it
immediately as a graph; I don't need JMC developers to change JMC for me.
Even better, I can select several metrics and display them in one graph.

But the latter functionality is stunted because it only works as long as
the metrics are from the same Event. So, for example, I can create a filter
from "jdk.G1HeapSummary" and build myself a nice view of the different G1
generation sizes. But I cannot correlate that e.g., with Metrics from
"jdk.MetaspaceSummary" and "jdk.ResidentSetSize" to display class space
size, heap generation sizes, and RSS in the same graph (when I try to do
this - build up a filter from multiple event types - the "Show In Line
Chart" Sub menu is empty).

Is there a way to select metrics from different Events into a chart that I
don't see?

I have a similar problem with the Table view of Events in Event Filters
that are formed from multiple Event Types. It only shows the set of fields
present in all events, so it is an inner join. I would like to see an outer
join - show me all fields from all events, and leave those fields blank
that don't match a given event type.

Is that possible? Am I doing something wrong?

Thank you!

Thomas
