EXPORTS¶
start(Filename::string()) -> {ok, Port} | {already_started, Port}
Equivalent to start(Filename, [procs]).
start(Filename::string(), Options::[percept_option()]) -> {ok, Port} |
{already_started, Port}
Types:
Port = 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::string(), MFA::mfa(), Options::[percept_option()]) -> ok |
{already_started, Port} | {error, not_started}
Types:
Port = port()
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.
