Types ¶
type SpanLogger ¶
type SpanLogger struct {
log.Logger
opentracing.Span
}
SpanLogger unifies tracing and logging, to reduce repetition.
func FromContext ¶ added in v0.7.0
func FromContext(ctx context.Context) *SpanLogger
FromContext returns a span logger using the current parent span. If there is no parent span, the SpanLogger will only log to the logger in the context. If the context doesn't have a logger, the global logger is used.
func FromContextWithFallback ¶ added in v1.6.0
func FromContextWithFallback(ctx context.Context, fallback log.Logger) *SpanLogger
FromContextWithFallback returns a span logger using the current parent span. IF there is no parent span, the SpanLogger will only log to the logger within the context. If the context doesn't have a logger, the fallback logger is used.
func NewWithLogger ¶ added in v1.6.0
func NewWithLogger(ctx context.Context, l log.Logger, method string, kvps ...interface{}) (*SpanLogger, context.Context)
NewWithLogger makes a new SpanLogger with a custom log.Logger to send logs to. The provided context will have the logger attached to it and can be retrieved with FromContext or FromContextWithFallback.
func (*SpanLogger) Error ¶
func (s *SpanLogger) Error(err error) error
Error sets error flag and logs the error on the span, if non-nil. Returns the err passed in.
func (*SpanLogger) Log ¶
func (s *SpanLogger) Log(kvps ...interface{}) error
Log implements gokit's Logger interface; sends logs to underlying logger and also puts the on the spans.
