Overview
Percept Collector
This module provides the user interface for the percept data collection (profiling).
Data types
- percept_option() = procs | ports | exclusive:
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.
