	// EnvLogLevel is the environment variable that controls the default logger's level.

Functions

func SetDefaultLogger

func SetDefaultLogger(l *LevelLogger)

SetDefaultLogger sets the package default logger to the logger provided.

Types

type Level

type Level uint32

Level represents a log level.

const (
	TraceLevel Level = iota
	DebugLevel
	InfoLevel
	WarningLevel
	ErrorLevel
	CriticalLevel
	OffLevel
)

Log levels.

func ParseLogLevel

func ParseLogLevel(s string) (Level, error)

ParseLogLevel parses s as a log level.

func (Level) String

func (l Level) String() string

type LevelLogger

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

LevelLogger is a level logging implementation that will log to a file, stdout, or stderr. The level may be updated dynamically via SetLevel.

func DefaultLogger

func DefaultLogger() *LevelLogger

DefaultLogger initialises defaultLogger using the environment variables ELASTIC_APM_LOG_FILE and ELASTIC_APM_LOG_LEVEL. If defaultLogger is non-nil, it returns the logger.

func (*LevelLogger) Debugf

func (l *LevelLogger) Debugf(format string, args ...interface{})

Debugf logs a message with log.Printf, with a DEBUG prefix.

func (*LevelLogger) Errorf

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

Errorf logs a message with log.Printf, with an ERROR prefix.

func (*LevelLogger) Level

func (l *LevelLogger) Level() Level

Level returns the current logging level.

func (*LevelLogger) SetLevel

func (l *LevelLogger) SetLevel(level Level)

SetLevel sets level as the minimum logging level.

func (*LevelLogger) Warningf

func (l *LevelLogger) Warningf(format string, args ...interface{})

Warningf logs a message with log.Printf, with a WARNING prefix.
