HI Evan, I just noticed you attached the trace file.
You need to make a custom analysis for this as your events are freeform.
You can try the incubator's callstack. But I suspect a simple XML gantt chart (works out of the box) would suit your needs.

Hi Evan,
the setup of the tracer looks OK, but do you have entry/exit events. If they are non-standard cyg-profile ones, look at the incubator, you can set up an XML configuration to handle your trace format.

I am having trouble getting the flame graph (both normal and incubator) to show the call stack of my Java program. I know I am missing something but am not sure what I need to do. The commands I am using are as follows:
lttng start
lttng enable-event --u --u
lttng add-context -u -t vpid -t vtid -t procname lttng enable-event --jul myLogger
On the Flame Chart I see a message that says that the stack info is not available for Kernel/UST. Could this be relevant?
I am using trace compass 7.0.0, lttng 2.12.4 , and lttng tools 2.12 I have attached a trace file that I am working with
Thank you for your time
