Functions

func Errorf

func Errorf(format string, args ...interface{})

Errorf logs error message.

func ErrorfSkipframes

func ErrorfSkipframes(skipframes int, format string, args ...interface{})

func StdErrorLogger

func StdErrorLogger() *log.Logger

StdErrorLogger returns standard error logger.

func Warnf

func Warnf(format string, args ...interface{})

Types

type LogThrottler

type LogThrottler struct {
	// contains filtered or unexported fields
}

LogThrottler is a logger, which throttles log messages passed to Warnf and Errorf.

LogThrottler must be created via WithThrottler() call.

func WithThrottler

func WithThrottler(name string, throttle time.Duration) *LogThrottler

WithThrottler returns a logger throttled by time - only one message in throttle duration will be logged.

New logger is created only once for each unique name passed. The function is thread-safe.

func (*LogThrottler) Errorf

func (lt *LogThrottler) Errorf(format string, args ...interface{})

Errorf logs error message.

func (*LogThrottler) Warnf

func (lt *LogThrottler) Warnf(format string, args ...interface{})

Warnf logs warn message.
