clear_all_traces() -> any()
clear_trace_by_destination(ID) -> any()
dispatch_log(Severity, Metadata, Format, Args, Size) -> any()
dispatch_log(Sink::atom(), Severity::log_level(), Metadata::list(), Format::string(), Args::list() | none, Size::pos_integer(), Safety::safe | unsafe) -> ok | {error, lager_not_running} | {error, {sink_not_configured, atom()}}

do_log(Severity, Metadata, Format, Args, Size, SeverityAsInt, LevelThreshold, TraceFilters, SinkPid) -> any()
get_loglevel(Handler) -> any()
Get the loglevel for a particular backend on the default sink. In the case that the backend has multiple identifiers, the lowest is returned.
get_loglevel(Sink, Handler) -> any()
Get the loglevel for a particular sink's backend. In the case that the backend has multiple identifiers, the lowest is returned.
install_trace(Pid::pid(), Level::log_level()) -> ok
installs a lager trace handler into the target process (using sys:install) at the specified level.
install_trace(Pid::pid(), Level::log_level(), Options::[{count, infinity | pos_integer()} | {format_string, string()} | {timeout, timeout()}]) -> ok
list_all_sinks() -> any()
log(Level::log_level(), Pid::pid() | atom() | [tuple(), ...], Message::list()) -> ok | {error, lager_not_running}
Manually log a message into lager without using the parse transform.
log(Level::log_level(), Pid::pid() | atom() | [tuple(), ...], Format::string(), Args::list()) -> ok | {error, lager_not_running}
Manually log a message into lager without using the parse transform.
log(Sink::atom(), Level::log_level(), Pid::pid() | atom() | [tuple(), ...], Format::string(), Args::list()) -> ok | {error, lager_not_running}
Manually log a message into lager without using the parse transform.
log_unsafe(Level, Metadata, Format, Args) -> any()
md() -> [{atom(), any()}]
Get lager metadata for current process
md(NewMD::[{atom(), any()}, ...]) -> ok
Set lager metadata for current process. Will badarg if you don't supply a list of {key, value} tuples keyed by atoms.
posix_error(Error) -> any()
Try to convert an atom to a posix error, but fall back on printing the term if its not a valid posix error code.
pr(Record, Module) -> any()
Print a record or a list of records lager found during parse transform
pr(Record, Module, Options) -> any()
Print a record or a list of records lager found during parse transform

remove_trace(Pid::pid()) -> ok
remove a previously installed lager trace handler from the target process.
rotate_all() -> any()
rotate_handler(Handler) -> any()
rotate_handler(Handler, Sink) -> any()
rotate_sink(Sink) -> any()
safe_format(Fmt, Args, Limit) -> any()
Print the format string Fmt with Args safely with a size
limit of Limit. If the format string is invalid, or not enough
arguments are supplied 'FORMAT ERROR' is printed with the offending
arguments. The caller is NOT crashed.
set_loghwm(Handler, Hwm) -> any()
Set the loghwm for the default sink.
set_loghwm(Sink, Handler, Hwm) -> any()
Set the loghwm for a particular backend.

set_loglevel(Handler, Level) -> any()
Set the loglevel for a particular backend.
set_loglevel(Handler, Ident, Level) -> any()
Set the loglevel for a particular backend that has multiple identifiers (eg. the file backend).
set_loglevel(Sink, Handler, Ident, Level) -> any()
Set the loglevel for a particular sink's backend that potentially has
multiple identifiers. (Use undefined if it doesn't have any.)
start() -> any()
Start the application. Mainly useful for using -s lager as a command
line switch to the VM to make lager start on boot.
status() -> any()
stop_trace(X1) -> any()
stop_trace(Backend, Filter, Level) -> any()
trace(Backend, Filter) -> any()
trace(Backend, Filter, Level) -> any()

update_loglevel_config(Sink) -> any()
recalculate min log level
