mProfiler is a lightweight, header-only C++ tool for measuring execution time of your code. It features an averaging mechanism and registers min and max values. It can be easily reseted for monitoring of continuous functions. mProfiler's data can be accessed directly, pretty-printed or returned as CSV.
There are two examples available:
Showcases a regular - single shot - mode for measuring execution time of a block of code.
$ ./regular
Results:
[Profiler Internal Loop 1] Average: 5.94ms, Min: 81us, Max: 9.863ms
[Profiler Internal Loop 2] Average: 7.373ms, Min: 5.167ms, Max: 10.97ms
[Profiler External Loop] Average: 1.246998s, Min: 1.246998s, Max: 1.246998s
Designed to measure periodically executed tasks, such as control loops Example output:
$ ./continuous

The profiler simouteniosly relays data to profiler_log.txt file in CSV format:
$ cat profiler_log.txt
Average, Min, Max

1231, 1043, 1412
1230, 1051, 1364
1227, 1060, 1829
