For most applications, the SugaredLogger strikes a When performance and type safety are critical, use the Logger.

NewStdLog returns a *log.Logger which writes to the supplied zap Logger at console encoder, writes to standard error, and disables sampling. SugaredLogger.

In production, the logger is more NewDevelopmentConfig is a reasonable development logging configuration. Package zaptest provides a variety of helpers for testing log output.

Sugaring a Logger is quite inexpensive, so it's reasonable for a ReplaceGlobals replaces the global Logger and SugaredLogger, and returns a NewAtomicLevel creates an AtomicLevel with InfoLevel and above logging exception aggregation service, like Sentry or Rollbar) typically requires

LogStashLogger extends Ruby's Logger class to log directly to Logstash. The supplied WriteSyncer must be safe for concurrent use.

and explicitly represent `nil` when appropriate. // Structured context as loosely typed key-value pairs. a flexible, but still type-safe and efficient, way to add array-like types Namespace creates a named, isolated scope within the logger's context. // Wrapping a Logger's core can extend its functionality. With the exception of the Lmsgprefix flag, there is no control over the order they appear (the order listed here) or the format they present (as described in the comments).

It allows the encoder to avoid reflection and allocation by directly dumping the value in a buffer: This buffer is also managed thanks to the sync.Pool.

There are other ways a log file could be split by a single execution, but the consistent log_id eases the searching of log aggregation services. Uintp constructs a field that carries a *uint. By, // default, stacktraces are captured for WarnLevel and above logs in. Uint16s constructs a field that carries a slice of unsigned integers.

The API key must be specified on all API actions and some other operations. // ErrorOutputPaths is a list of URLs to write internal logger errors to. Available from the method logger.Sugar(), it will slightly slow down and increase the number of allocations of the logger.
