Percept - Erlang Concurrency Profiling Tool
This module provides the user interface for the application.
analyze(Filename::string()) -> ok | {error, Reason}
profile(Filename::string()) -> {ok, Port} | {already_started, Port}
Equivalent to profile(Filename, [procs]).
profile(Filename::string(), Options::[profile_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_profile/0 is needed to stop profiling.
See also: stop_profile/0.
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_profile/0 is needed, the profiling stops when the entry function returns.
start_webserver() -> {started, Hostname, Port} | {error, Reason}
Types:
Hostname = string()
Port = integer()
Reason = term()
start_webserver(Port::integer()) -> {started, Hostname, AssignedPort} | {error, Reason}
Types:
Hostname = string()
AssignedPort = integer()
Reason = term()
stop_profile() -> ok | {error, not_started}
stop_webserver() -> ok | {error, not_started}
