+## Run profiler in a loop

+Use `--loop TIME` to run profiler in a loop (continuous profiling). The argument is either a clock time (hh:mm:ss) or a loop duration in seconds, minutes, hours, or days. Make sure the filename includes a timestamp pattern, or the output will be overwritten on each iteration. The command below will run profiling endlessly and save records of each hour to a jfr file.

+## `--timeout` option
+
+This option specifies the time when profiling will automatically stop. The format is the same as in loop: it is either a wall clock time (12:34:56) or a relative time interval (2h).
+
+Both `--loop` and `--timeout` are used for `start` action but not for `collect` action, for further information refer to [async-profiler Github Discussions](https://github.com/async-profiler/async-profiler/discussions/789).
