Hi Vivek, When reporting an issue, please provide:
- lttng-sessiond verbose logs, debug logs, - detailed command line usage, in text-only format. Sorry, we're kind of busy, so don't expect us to dig this information from attachments. The best way to do this is to file a bug on bugs.lttng.org, so we can track the issue.
