// Package level implements leveled logging on top of Go kit's log package. To
|
|
// use the level package, create a logger as per normal in your func main, and
|
|
// wrap it with level.NewFilter.
|
|
//
|
|
// var logger log.Logger
|
|
// logger = log.NewLogfmtLogger(os.Stderr)
|
|
// logger = level.NewFilter(logger, level.AllowInfo()) // <--
|
|
// logger = log.With(logger, "ts", log.DefaultTimestampUTC)
|
|
//
|
|
// Then, at the callsites, use one of the level.Debug, Info, Warn, or Error
|
|
// helper methods to emit leveled log events.
|
|
//
|
|
// logger.Log("foo", "bar") // as normal, no level
|
|
// level.Debug(logger).Log("request_id", reqID, "trace_data", trace.Get())
|
|
// if value > 100 {
|
|
// level.Error(logger).Log("value", value)
|
|
// }
|
|
//
|
|
// NewFilter allows precise control over what happens when a log event is
|
|
// emitted without a level key, or if a squelched level is used. Check the
|
|
// Option functions for details.
