I'm so sorry. I don't know a proper repo where to submit this issue.
HOST OS: Ubuntu 20.04.1 LTS
used command for tracing:
error log:
aero@aero:~/ros/freertos$ ros2 trace
UST tracing enabled (16 events)
kernel tracing enabled (4 events)
context (3 names)
writing tracing session to: /home/aero/.ros/tracing/session-20201021211759
press enter to start...
channel enabling failed: Tracing the kernel requires a root lttng-sessiond daemon, as well as "tracing" group membership or root user ID for the lttng client.
I'v done everything mentioned in the tutorial https://micro-ros.github.io/docs/tutorials/advanced/tracing
but i'm stuck at this step ros2 launch tracetools_launch example.launch.py, which report similar error about Tracing the kernel requires a root lttng-sessiond daemon, as well as "tracing" group membership or root user ID for the lttng client
