Percept Collector
This module provides the user interface for the percept data collection (profiling).percept_option() = procs | ports | exclusive | scheduler
| start/1 | Equivalent to start(Filename, [procs]).
|
| start/2 | Starts profiling with supplied options. |
| start/3 | Starts profiling at the entrypoint specified by the MFA. |
| stop/0 | Stops profiling. |
start(Filename::file:filename()) -> {ok, port()} | {already_started, port()}
Equivalent to start(Filename, [procs]).
start(Filename::file:filename(), Options::[percept_option()]) -> {ok, port()} | {already_started, port()}
Starts profiling with supplied options. All events are stored in the file given by Filename. An explicit call to stop/0 is needed to stop profiling.
start(Filename::file:filename(), Entry::{atom(), atom(), list()}, Options::[percept_option()]) -> ok | {already_started, port()} | {error, not_started}
Starts profiling at the entrypoint specified by the MFA. All events are collected, this means that processes outside the scope of the entry-point are also profiled. No explicit call to stop/0 is needed, the profiling stops when the entry function returns.
stop() -> ok | {error, not_started}
Stops profiling.
