I realized I didn’t introduce a good, intuitive example use case of DAMON[0] for profiling so far, though DAMON is not for only profiling. One straightforward and realistic usage of DAMON as a profiling tool would be recording the monitoring results with callstack and visualize those by timeline together.
For example, below shows that visualization for a realistic workload, namely ‘fft’ in SPLASH-2X benchmark suite. The upper-most graph shows how DAMON-detected working set size of the workload (y-axis) changes by time (x-axis).
