Zephyr Profiling

[svetelna]

Hello,
I would like to make a profiling of a Zephyr application.
So far, I have found the "Footprint and Memory Usage" static analysis [1], "Timing functions" for measuring the execution time of a code section [2], and "Thread Analyzer" [3] for getting stack and CPU runtime usage of the threads.

However, I did not found out how to collect heap info (heap usage) during runtime and CPU time spent on specific tasks.
Is there any possibility of collecting this information?

I think you could use sys_heap_print_info: https://github.com/zephyrproject-rtos/zephyr/blob/master/lib/os/heap-validate.c#L386
