NAME
percept_profile - Percept Collector.
DESCRIPTION
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.
