Overview

Package grpclog defines logging for grpc.

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 Error

func Error(args ...any)

Error logs to the ERROR log.

func ErrorDepth

func ErrorDepth(depth int, args ...any)

ErrorDepth logs to the ERROR log at the specified depth.

Experimental

Notice: This API is EXPERIMENTAL and may be changed or removed in a later release.

func Errorf

func Errorf(format string, args ...any)

Errorf logs to the ERROR log. Arguments are handled in the manner of fmt.Printf.

func Errorln

func Errorln(args ...any)

Errorln logs to the ERROR log. Arguments are handled in the manner of fmt.Println.

func Fatal

func Fatal(args ...any)

Fatal logs to the FATAL log. Arguments are handled in the manner of fmt.Print. It calls os.Exit() with exit code 1.

func FatalDepth

func FatalDepth(depth int, args ...any)

FatalDepth logs to the FATAL log at the specified depth.

Experimental

Notice: This API is EXPERIMENTAL and may be changed or removed in a later release.

func Fatalf

func Fatalf(format string, args ...any)

Fatalf logs to the FATAL log. Arguments are handled in the manner of fmt.Printf. It calls os.Exit() with exit code 1.

func Fatalln

func Fatalln(args ...any)

Fatalln logs to the FATAL log. Arguments are handled in the manner of fmt.Println. It calls os.Exit() with exit code 1.

func Info

func Info(args ...any)

Info logs to the INFO log.

func InfoDepth

func InfoDepth(depth int, args ...any)

InfoDepth logs to the INFO log at the specified depth.

Experimental

Notice: This API is EXPERIMENTAL and may be changed or removed in a later release.

func Infof

func Infof(format string, args ...any)

Infof logs to the INFO log. Arguments are handled in the manner of fmt.Printf.

func Infoln

func Infoln(args ...any)

Infoln logs to the INFO log. Arguments are handled in the manner of fmt.Println.

func Print

func Print(args ...any)

Print prints to the logger. Arguments are handled in the manner of fmt.Print.

Deprecated: use Info.

func Printf

func Printf(format string, args ...any)

Printf prints to the logger. Arguments are handled in the manner of fmt.Printf.

Deprecated: use Infof.

func Println

func Println(args ...any)

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

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

func V(l int) bool

V reports whether verbosity level l is at least the requested verbose level.

func Warning

func Warning(args ...any)

Warning logs to the WARNING log.

func WarningDepth

func WarningDepth(depth int, args ...any)

WarningDepth logs to the WARNING log at the specified depth.

Experimental

Notice: This API is EXPERIMENTAL and may be changed or removed in a later release.

func Warningf

func Warningf(format string, args ...any)

Warningf logs to the WARNING log. Arguments are handled in the manner of fmt.Printf.

func Warningln

func Warningln(args ...any)

Warningln logs to the WARNING log. Arguments are handled in the manner of fmt.Println.

Types

type DepthLoggerV2

type DepthLoggerV2 internal.DepthLoggerV2

DepthLoggerV2 logs at a specified call frame. If a LoggerV2 also implements DepthLoggerV2, the below functions will be called with the appropriate stack depth set for trivial functions the logger may ignore.

Experimental

Notice: This type is EXPERIMENTAL and may be changed or removed in a later release.

func Component

func Component(componentName string) DepthLoggerV2

Component creates a new component and returns it for logging. If a component with the name already exists, nothing will be created and it will be returned. SetLoggerV2 will panic if it is called with a logger created by Component.

type Logger

type Logger internal.Logger

Logger mimics golang's standard Logger as an interface.

Deprecated: use LoggerV2.

type LoggerV2

type LoggerV2 internal.LoggerV2

LoggerV2 does underlying logging work for grpclog.

func NewLoggerV2

func NewLoggerV2(infoW, warningW, errorW io.Writer) LoggerV2

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.

func NewLoggerV2WithVerbosity

func NewLoggerV2WithVerbosity(infoW, warningW, errorW io.Writer, v int) LoggerV2

NewLoggerV2WithVerbosity creates a loggerV2 with the provided writers and verbosity level.
