Functions

func BuildZapLogger added in v1.5.7 

func BuildZapLogger(cfg Config) *zap.Logger

BuildZapLogger builds and returns a new zap.Logger for this logging configuration

func CapturePanic 

func CapturePanic(logger Logger, retError *error)

CapturePanic is used to capture panic, it will log the panic and also return the error through pointer. If the panic value is not error then a default error is returned We have to use pointer is because in golang: "recover return nil if was not called directly by a deferred function." And we have to set the returned error otherwise our handler will return nil as error which is incorrect

func NewCLILogger added in v1.10.0 

func NewCLILogger() *zapLogger

NewCLILogger returns a logger at debug level and log into STDERR for logging from within CLI tools

func NewLazyLogger added in v1.17.0 

func NewLazyLogger(logger Logger, tagFn func() []tag.Tag) *lazyLogger

func NewNoopLogger added in v1.5.7 

func NewNoopLogger() *noopLogger

NewNoopLogger return a noopLogger

func NewReplayLogger added in v1.5.7 

func NewReplayLogger(logger Logger, ctx workflow.Context, enableLogInReplay bool) *replayLogger

NewReplayLogger creates a logger which is aware of Temporal replay mode

func NewTestLogger added in v1.10.0 

func NewTestLogger() *zapLogger

NewTestLogger returns a logger for tests

func NewThrottledLogger added in v1.5.7 

func NewThrottledLogger(logger Logger, rps quotas.RateFn) *throttledLogger

NewThrottledLogger returns an implementation of logger that throttles the log messages being emitted. The underlying implementation uses a token bucket rate limiter and stops emitting logs once the bucket runs out of tokens

Fatal/Panic logs are always emitted without any throttling

func NewZapLogger added in v1.5.7 

func NewZapLogger(zl *zap.Logger) *zapLogger

NewZapLogger returns a new zap based logger from zap.Logger

Types

type Config added in v1.5.7 

type Config struct {
	// Stdout is true if the output needs to goto standard out; default is stderr
	Stdout bool `yaml:"stdout"`
	// Level is the desired log level; see colocated zap_logger.go::parseZapLevel()
	Level string `yaml:"level"`
	// OutputFile is the path to the log output file
	OutputFile string `yaml:"outputFile"`
	// Format determines the format of each log file printed to the output.
	// Acceptable values are "json" or "console". The default is "json".
	// Use "console" if you want stack traces to appear on multiple lines.
	Format string `yaml:"format"`
	// Development determines whether the logger is run in Development (== Test) or in
	// Production mode.  Default is Production.  Production-stage disables panics from
	// DPanic logging.
	Development bool `yaml:"development"`
}

Config contains the config items for logger

type Logger 

type Logger interface {
	Debug(msg string, tags ...tag.Tag)
	Info(msg string, tags ...tag.Tag)
	Warn(msg string, tags ...tag.Tag)
	Error(msg string, tags ...tag.Tag)
	DPanic(msg string, tags ...tag.Tag)
	Panic(msg string, tags ...tag.Tag)
	Fatal(msg string, tags ...tag.Tag)
}

Logger is the logging interface. Usage example: 

 logger.Info("hello world",
         tag.WorkflowNextEventID(123),
         tag.WorkflowActionWorkflowStarted,
         tag.WorkflowNamespaceID("test-namespace-id")),
	 )
 Note: msg should be static, do not use fmt.Sprintf() for msg. Anything dynamic should be tagged.
