Hi there

Thanks for help on my previous issue. I was able to get callstack-user= =C2=A0to work and see it in my traces. However, in order to get it to run I= needed to enable-event --kernel all. Is it necessary to have all kernel ev= ents enabled to run callstack-user? Or is it just one specific event?

When I try to run it without enabling a= ll kernel events the command is accepted and it runs but I get the followin= g error when trying to view my traces:
