[tracecompass-dev] Having trouble using Flame Chart

[Evan Galea <evanjamesgalea@xxxxxxxxx>]

Hi

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

Evan Galea
