Hi.
I don't know how to monitor the performance of our application, that is running in Linux agl on a Qualcomm S820A hardware platform.
Linux agl stands for Automotive Grade Linux, https://www.automotivelinux.org.
Our processes are *not* shown in Data Source.
I note Snapdragon Profiler can monitor all Active User processes. but that is only available in Android
Is it totally impossible to monitor process performance in Linux AGL?
Any other solutions for my case?
Thanks for help.

Which mode of Profiler are you using (Realtime, Trace, or Snapshot)? Is the process list completely empty or is it just missing your processes?
Eric
Hi, Eric.
I'm glad to have your reply.
I tried Realtime and Trace mode. my processes are missing in both modes.
I prepared some screen shots for your investigation.

Currently the only process specific trace metrics supported in Profiler are GPU related, so you will only see processes listed in Trace mode if they use OpenGL or Vulkan. If your process does use OpenGL or Vulkan, please ensure you connect Profiler to the device before starting your process.
In Realtime mode, processes with an owner of 'root' or 'system' are filtered out of the list. Does this apply to the process you would like to monitor? If so, is it possible to run the process as a different user?
Eric
Thanks again.
Our application can be launched as a normal user.
I have another question about profiling task.
Some part of our application such as SLAM need be running in ARM CPU,
Trace metrics in Snapdragon Profiler are only GPU related, therefore I need other tools to analyse the trace-based profiling, not just %cpu, %memory metric.
I had planned to port oprofiler tool for this platform. but it turns out that oprofiler source code doesn't support Kryo™ CPU in S820 Soc.
Could you kindly suggest any other tools that can be used for Linux agl on S820 platform?
thanks.
Tao
I succeeded in porting the Linux perf tool on S820 platform.
it will cover the most perfr profiling task.
Thanks
