Overview ¶
Package grpclog defines logging for grpc.
All logs in transport package only go to verbose level 2. All logs in other packages in grpc are logged in spite of the verbosity level.
In the default logger, severity level can be set by environment variable GRPC_GO_LOG_SEVERITY_LEVEL, verbosity level can be set by GRPC_GO_LOG_VERBOSITY_LEVEL.

Functions ¶
func Errorf ¶ added in v1.5.0
func Errorf(format string, args ...interface{})
Errorf logs to the ERROR log. Arguments are handled in the manner of fmt.Printf.
func Errorln ¶ added in v1.5.0
func Errorln(args ...interface{})
Errorln logs to the ERROR log. Arguments are handled in the manner of fmt.Println.
func Fatal ¶
func Fatal(args ...interface{})
Fatal logs to the FATAL log. Arguments are handled in the manner of fmt.Print. It calls os.Exit() with exit code 1.
func Fatalf ¶
func Fatalf(format string, args ...interface{})
Fatalf logs to the FATAL log. Arguments are handled in the manner of fmt.Printf. It calles os.Exit() with exit code 1.
func Fatalln ¶
func Fatalln(args ...interface{})
Fatalln logs to the FATAL log. Arguments are handled in the manner of fmt.Println. It calle os.Exit()) with exit code 1.
func Infof ¶ added in v1.5.0
func Infof(format string, args ...interface{})
Infof logs to the INFO log. Arguments are handled in the manner of fmt.Printf.
func Infoln ¶ added in v1.5.0
func Infoln(args ...interface{})
Infoln logs to the INFO log. Arguments are handled in the manner of fmt.Println.
func Print ¶
func Print(args ...interface{})
Print prints to the logger. Arguments are handled in the manner of fmt.Print. Deprecated: use Info.
func Printf ¶
func Printf(format string, args ...interface{})
Printf prints to the logger. Arguments are handled in the manner of fmt.Printf. Deprecated: use Infof.
func Println ¶
func Println(args ...interface{})
Println prints to the logger. Arguments are handled in the manner of fmt.Println. Deprecated: use Infoln.
func SetLogger ¶
func SetLogger(l Logger)
SetLogger sets the logger that is used in grpc. Call only from init() functions. Deprecated: use SetLoggerV2.
func SetLoggerV2 ¶ added in v1.5.0
func SetLoggerV2(l LoggerV2)
SetLoggerV2 sets logger that is used in grpc to a V2 logger. Not mutex-protected, should be called before any gRPC functions.
func V ¶ added in v1.5.0
V reports whether verbosity level l is at least the requested verbose level.
Types ¶
type Logger ¶
type Logger interface {
Fatal(args ...interface{})
Fatalf(format string, args ...interface{})
Fatalln(args ...interface{})
Print(args ...interface{})
Printf(format string, args ...interface{})
Println(args ...interface{})
}
Logger mimics golang's standard Logger as an interface. Deprecated: use LoggerV2.
type LoggerV2 ¶ added in v1.5.0
type LoggerV2 interface {
// Info logs to INFO log. Arguments are handled in the manner of fmt.Print.
Info(args ...interface{})
// Infoln logs to INFO log. Arguments are handled in the manner of fmt.Println.
Infoln(args ...interface{})
// Infof logs to INFO log. Arguments are handled in the manner of fmt.Printf.
Infof(format string, args ...interface{})
// Warning logs to WARNING log. Arguments are handled in the manner of fmt.Print.
Warning(args ...interface{})
// Warningln logs to WARNING log. Arguments are handled in the manner of fmt.Println.
Warningln(args ...interface{})
// Warningf logs to WARNING log. Arguments are handled in the manner of fmt.Printf.
Warningf(format string, args ...interface{})
// Error logs to ERROR log. Arguments are handled in the manner of fmt.Print.
Error(args ...interface{})
// Errorln logs to ERROR log. Arguments are handled in the manner of fmt.Println.
Errorln(args ...interface{})
// Errorf logs to ERROR log. Arguments are handled in the manner of fmt.Printf.
Errorf(format string, args ...interface{})
// Fatal logs to ERROR log. Arguments are handled in the manner of fmt.Print.
// gRPC ensures that all Fatal logs will exit with os.Exit(1).
// Implementations may also call os.Exit() with a non-zero exit code.
Fatal(args ...interface{})
// Fatalln logs to ERROR log. Arguments are handled in the manner of fmt.Println.
// gRPC ensures that all Fatal logs will exit with os.Exit(1).
// Implementations may also call os.Exit() with a non-zero exit code.
Fatalln(args ...interface{})
// Fatalf logs to ERROR log. Arguments are handled in the manner of fmt.Printf.
// gRPC ensures that all Fatal logs will exit with os.Exit(1).
// Implementations may also call os.Exit() with a non-zero exit code.
Fatalf(format string, args ...interface{})
// V reports whether verbosity level l is at least the requested verbose level.
V(l int) bool
}
LoggerV2 does underlying logging work for grpclog.
func NewLoggerV2 ¶ added in v1.5.0
NewLoggerV2 creates a loggerV2 with the provided writers. Fatal logs will be written to errorW, warningW, infoW, followed by exit(1). Error logs will be written to errorW, warningW and infoW. Warning logs will be written to warningW and infoW. Info logs will be written to infoW.
