Functions

func MakeBaseLogger

func MakeBaseLogger(ctx context.Context, logLevel string) context.Context

func NewTestLogger

func NewTestLogger(t testing.TB, level dlog.LogLevel) dlog.Logger

func SetLevel

func SetLevel(ctx context.Context, logLevelStr string)

SetLevel sets the log-level for the logger of the given context.

func SetLogrusLevel

func SetLogrusLevel(logrusLogger *logrus.Logger, logLevelStr string, logChange bool)

SetLogrusLevel sets the log-level of the given logger from logLevelStr and logs that to the logger.

func WithDiscardingLogger

func WithDiscardingLogger(ctx context.Context) context.Context

WithDiscardingLogger returns a context that discards all log output.

func WithLevelSetter

func WithLevelSetter(ctx context.Context, logrusLogger *logrus.Logger) context.Context

WithLevelSetter enables setting the log-level of the given Logger by using the returned context as an argument to the SetLevel function.

Types

type Formatter

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

Formatter formats log messages for Telepresence.

func NewFormatter

func NewFormatter(timestampFormat string) *Formatter

func (*Formatter) Format

func (f *Formatter) Format(entry *logrus.Entry) ([]byte, error)

Format implements logrus.Formatter.

type LevelSetter

type LevelSetter func(ctx context.Context, logLevel string)

LevelSetter is a function that sets the log-level.

type TimedLevel

type TimedLevel interface {
	sync.Locker

	// Get returns the current level and the time left until that level
	// is reset to default. An empty string and zero is returned if
	// no level has been set or if it has expired already.
	Get() (string, time.Duration)

	// Set sets a new log-level that will be active for the given duration. If the
	// duration is zero, then the log-level will be active until the next call to
	// Set. If level is the empty string, then duration is ignored and the log-level
	// will be reset to default.
	Set(ctx context.Context, level string, duration time.Duration)

	// Reset restores the log-level to its default value
	Reset(ctx context.Context)
}

TimedLevel is an object capable of setting a log-level for a given time period and then resetting it to a default.

func NewTimedLevel

func NewTimedLevel(defaultLevel string, setter LevelSetter) TimedLevel

NewTimedLevel returns a new TimedLevel for the given default level and setter.
