Functions

func NewLogger

func NewLogger(cfg Config) logrus.FieldLogger

NewLogger returns a new logger that includes app and deploy key/value pairs in each log line.

func NewSampleLogger

func NewSampleLogger(parentLogger logrus.FieldLogger, logsBurstLimit int, logBurstWindow time.Duration) logrus.FieldLogger

NewSampleLogger creates a rate limited logger that samples logs. The parameter logsBurstLimit defines how many logs are allowed per logBurstWindow duration. The returned logger derives from the parentLogger, but without inheriting any Hooks. All log entries derived from SampleLogger will contain 'sampled=true' field.

func SaramaLogger

func SaramaLogger(logger logrus.FieldLogger) logrus.FieldLogger

SaramaLogger takes FieldLogger and returns a saramaLogger.
