Constants

const (

	// CsiRequestID use to mark requestId for log printer
	CsiRequestID key = "csi.requestid"

	// TagNameKey use to mark tag name key
	TagNameKey key = "csi.tag"

	// TagName use to mark tag for log printer
	TagName = "tag"
)

Functions

func Close

func Close()

Close ensures closing output stream

func Debugf

func Debugf(format string, args ...interface{})

Debugf ensures output of formatted debug logs

func Debugln

func Debugln(args ...interface{})

Debugln ensures output of Debug logs

func EnsureGRPCContext

func EnsureGRPCContext(ctx context.Context, req interface{},
	info *grpc.UnaryServerInfo,
	handler grpc.UnaryHandler) (interface{}, error)

EnsureGRPCContext ensures adding request id in incoming context

func Errorf

func Errorf(format string, args ...interface{})

Errorf ensures output of formatted error logs

func Errorln

func Errorln(args ...interface{})

Errorln ensures output of error logs

func Fatalf

func Fatalf(format string, args ...interface{})

Fatalf ensures output of formatted fatal logs

func Fatalln

func Fatalln(args ...interface{})

Fatalln ensures output of fatal logs

func FilteredLog

func FilteredLog(ctx context.Context, isSkip, isDebug bool, msg string)

FilteredLog will not print the logs that need to be filtered, and the log level will be as required.

func Flush

func Flush()

Flush ensures to commit current content of logging stream

func Infof

func Infof(format string, args ...interface{})

Infof ensures output of formatted info logs

func Infoln

func Infoln(args ...interface{})

Infoln ensures output of info logs

func InitLogging

func InitLogging(req *Config) error

InitLogging configures logging. Logs are written to a log file or stdout/stderr. Since logrus doesn't support multiple writers, each log stream is implemented as a hook.

func MockInitLogging

func MockInitLogging(logName string)

MockInitLogging mock init the logging service

func MockStopLogging

func MockStopLogging(logName string)

MockStopLogging mock stop the logging service

func SetRequestInfo

func SetRequestInfo(ctx context.Context) (context.Context, error)

SetRequestInfo used to set the context with value

func SetRequestInfoWithTag

func SetRequestInfoWithTag(ctx context.Context, tag string) (context.Context, error)

SetRequestInfoWithTag set request tag

func Warningf

func Warningf(format string, args ...interface{})

Warningf ensures output of formatted warning logs

func Warningln

func Warningln(args ...interface{})

Warningln ensures output of warning logs
