JAVA flamegraph not showing the complete stack.

Open c3-pranjaysagar opened this issue 2 years ago • 1 comments

Steps followed

  • Complete tutorial for deploying the self hosted pixie
  • Find an issue where stack in the flamegraph shows the hexa-decimal values
  • based on the discussion on the issue https://github.com/pixie-io/pixie/issues/592#issue-1372204593 manually edited the pem daemonsets.
  • Hexadecimal values finally resolved to method calls

Current Issue

  • the y-depth stack trace is incomplete as many of the method calls are missing in the stack. At what point does the flamegraph cutoff the stack at the top?
  • Also on many stacks the value is interpreter[xx]

System information

java version - `openjdk version "17.0.2" Environment - currently Azure

Hi @c3-pranjaysagar ,

The best case scenario for debugging this is if you could supply a mostly self-contained way to reproduce the bug. If you have an application that you can create an image and a yaml for, we can create a cluster on Azure (or elsewhere) and deploy it and see the bug reproduce.

Is it possible to follow this route?

@c3-pranjaysagar We're not able to reproduce this right now, so closing. But feel free to re-open with more details, and we'll take a look!
