Hihi, there,

I am currently working on enabling lttng live mode over android usb adb.= Here is the situation, during debugging some network related issues, we do= nt want the trace data to be streamed via network to cause extra load to th= e system being profiled. Then we select to connect lttng-relayd with adb via port forwarding so that the da= ta is "forward" to the host.

Here is the set up and the problem:

for the device:  adb reverse tcp:5342 tcp:5342; adb reve= rse tcp:5343 tcp:5343; adb reverse tcp:5344 tcp:5344
Then starting up lttng with --live enabled.

What is expected:
lttng start streaming to the localhost.
What is seen:
the lttng-relayd failed to start. For unable binding to the socket.<= /p>

The cause of this issue:

both adb reverse and lttng relayd need binding to the socket which is co= nflict with each other.


So what I wanna ask is, for embedded system use cases, do we have succes= sful use cases among team that could stream the trace data in live mode to = the host with usb based adb? If not, any idea or suggestion to me on how to= process forward?

Amanda
