Yes. I was trying the lttng-live command just in the hope that I could get
the trace data stream. Then I used the babeltrace command to connect to the
target. It got connected to the target but no data stream were received in
output.

The following babeltrace command were used:
*1. To connect to target.*
babeltrace --input-format=lttng-live net://localhost/host/
169.254.106.131/my-session

*2. To retrieve the trace data.*
babeltrace --input-format=lttng-live net://localhost

I have attached the output for your reference.
