See the README.md file at the top of the source repository for details.

add_custom_handler/2	Add a custom handler module to the `sysmon_handler`.
call_custom_handler/2
call_custom_handler/3	Make a synchronous call to a `sysmon_handler` specific custom event handler.
get_config/0	Gets configuration.
start_link/0	Starts the server.
start_link/1	Start sysmon_handler filter process.
start_timer/0
stop_timer/0

add_custom_handler(Module, Args) -> any()

Add a custom handler module to the sysmon_handler.

See the source code of the sysmon_handler_example_handler:add_handler/0 function for a usage example.

call_custom_handler(Module, Call) -> any()

call_custom_handler(Module, Call, Timeout) -> any()

Make a synchronous call to a sysmon_handler specific custom event handler.

See the source code of the sysmon_handler_example_handler:get_call_count/0 function for a usage example.

get_config() -> [{atom(), term()}]

Gets configuration

start_link() -> {ok, Pid} | ignore | {error, Error}

Starts the server

start_link(MonitorProps) -> any()

Start sysmon_handler filter process

The MonitorProps arg is a property list that may contain zero or more of the following atoms:

gc Enable long garbage collection events. The minimum time (in milliseconds) is defined by the application sysmon_handler environment variable gc_ms_limit.
heap Enable process large heap events.
