A: Sampling the program at specific times, and do some statistics analysis.

It can be one of the following:

  • Reading Backtraces of the program for every 1000th cycles, and represent in flamegraph.
  • Reading Backtraces of the program for every 1000th cache miss, and represent in flamegraph.
  • Reading Backtraces of the program for every 10th memory allocation, and represent in flamegraph.
  • Get return address of the program for every 10th memory allocation, and show counts for every line.

Kind of triggers:
