Types

type Config

type Config struct {
	// Level is the minimum enabled logging level. Note that this is a dynamic
	// level, so calling Config.Level.SetLevel will atomically change the log
	// level of all loggers descended from this config.
	Level zap.AtomicLevel `json:"level" yaml:"level"`
	// Development puts the logger in development mode, which changes the
	// behavior of DPanicLevel and takes stacktraces more liberally.
	Development bool `json:"development" yaml:"development"`
	// DisableCaller stops annotating logs with the calling function's file
	// name and line number. By default, all logs are annotated.
	// 调用 log方法 的文件名和行号
	DisableCaller bool `json:"disableCaller" yaml:"disableCaller"`
	// DisableStacktrace completely disables automatic stacktrace capturing. By
	// default, stacktraces are captured for WarnLevel and above logs in
	// development and ErrorLevel and above in production.
	DisableStacktrace bool `json:"disableStacktrace" yaml:"disableStacktrace"`
	// Sampling sets a sampling policy. A nil SamplingConfig disables sampling.
	// 日志记录限流
	// 每秒日志数量为Initial，如果超过，则每 Thereafter 条才记录
	// 每秒计数器会重置
	Sampling *zap.SamplingConfig `json:"sampling" yaml:"sampling"`
	// Encoding sets the logger's encoding. Valid values are "json" and
	// "console", as well as any third-party encodings registered via
	// RegisterEncoder.
	Encoder zapcore.Encoder

	WriteSyncer zapcore.WriteSyncer

	InitialFields map[string]interface{} `json:"initialFields" yaml:"initialFields"`
