Variables ¶
var MaxSize uint64 = 1024 * 1024 * 1800
MaxSize is the maximum size of a log file in bytes.
var Stats struct { Info, Warning, Error OutputStats }
Stats tracks the number of lines of output and number of bytes per severity level. Values must be read with atomic.LoadInt64.
Functions ¶
func CopyStandardLogTo ¶
func CopyStandardLogTo(name string)
CopyStandardLogTo arranges for messages written to the Go "log" package's default logs to also appear in the Google logs for the named and lower severities. Subsequent changes to the standard log's default output location or format may break this behavior.
Valid names are "INFO", "WARNING", "ERROR", and "FATAL". If the name is not recognized, CopyStandardLogTo panics.
func Error ¶
func Error(args ...interface{})
Error logs to the ERROR, WARNING, and INFO logs. Arguments are handled in the manner of fmt.Print; a newline is appended if missing.
func ErrorDepth ¶
func ErrorDepth(depth int, args ...interface{})
ErrorDepth acts as Error but uses depth to determine which call frame to log. ErrorDepth(0, "msg") is the same as Error("msg").
func ErrorDepthf ¶
ErrorDepthf acts as Error but uses depth to determine which call frame to log. Arguments format and args act as Errorf.
func Errorf ¶
func Errorf(format string, args ...interface{})
Errorf logs to the ERROR, WARNING, and INFO logs. Arguments are handled in the manner of fmt.Printf; a newline is appended if missing.
func Errorln ¶
func Errorln(args ...interface{})
Errorln logs to the ERROR, WARNING, and INFO logs. Arguments are handled in the manner of fmt.Println; a newline is appended if missing.
func Exit ¶
func Exit(args ...interface{})
Exit logs to the FATAL, ERROR, WARNING, and INFO logs, then calls os.Exit(1). Arguments are handled in the manner of fmt.Print; a newline is appended if missing.
func ExitDepth ¶
func ExitDepth(depth int, args ...interface{})
ExitDepth acts as Exit but uses depth to determine which call frame to log. ExitDepth(0, "msg") is the same as Exit("msg").
func ExitDepthf ¶
ExitDepthf acts as Exit but uses depth to determine which call frame to log, Arguments format and args act as Exitf.
func Exitf ¶
func Exitf(format string, args ...interface{})
Exitf logs to the FATAL, ERROR, WARNING, and INFO logs, then calls os.Exit(1). Arguments are handled in the manner of fmt.Printf; a newline is appended if missing.
func Exitln ¶
func Exitln(args ...interface{})
Exitln logs to the FATAL, ERROR, WARNING, and INFO logs, then calls os.Exit(1).
func Fatal ¶
func Fatal(args ...interface{})
Fatal logs to the FATAL, ERROR, WARNING, and INFO logs, including a stack trace of all running goroutines, then calls os.Exit(255). Arguments are handled in the manner of fmt.Print; a newline is appended if missing.
func FatalDepth ¶
func FatalDepth(depth int, args ...interface{})
FatalDepth acts as Fatal but uses depth to determine which call frame to log. FatalDepth(0, "msg") is the same as Fatal("msg").
func FatalDepthf ¶
FatalDepthf acts as Fatal but uses depth to determine which call frame to log, Arguments format and args act as Exitf.
func Fatalf ¶
func Fatalf(format string, args ...interface{})
Fatalf logs to the FATAL, ERROR, WARNING, and INFO logs, including a stack trace of all running goroutines, then calls os.Exit(255). Arguments are handled in the manner of fmt.Printf; a newline is appended if missing.
func Fatalln ¶
func Fatalln(args ...interface{})
Fatalln logs to the FATAL, ERROR, WARNING, and INFO logs, including a stack trace of all running goroutines, then calls os.Exit(255). Arguments are handled in the manner of fmt.Println; a newline is appended if missing.
func Info ¶
func Info(args ...interface{})
Info logs to the INFO log. Arguments are handled in the manner of fmt.Print; a newline is appended if missing.
func InfoDepth ¶
func InfoDepth(depth int, args ...interface{})
InfoDepth acts as Info but uses depth to determine which call frame to log. InfoDepth(0, "msg") is the same as Info("msg").
func InfoDepthf ¶
InfoDepthf acts as Info but uses depth to determine which call frame to log, Arguments format and args act as Infof.
func Infof ¶
func Infof(format string, args ...interface{})
Infof logs to the INFO log. Arguments are handled in the manner of fmt.Printf; a newline is appended if missing.
func Infoln ¶
func Infoln(args ...interface{})
Infoln logs to the INFO log. Arguments are handled in the manner of fmt.Println; a newline is appended if missing.
func Warning ¶
func Warning(args ...interface{})
Warning logs to the WARNING and INFO logs. Arguments are handled in the manner of fmt.Print; a newline is appended if missing.
func WarningDepth ¶
func WarningDepth(depth int, args ...interface{})
WarningDepth acts as Warning but uses depth to determine which call frame to log. WarningDepth(0, "msg") is the same as Warning("msg").
func WarningDepthf ¶
WarningDepthf acts as Warning but uses depth to determine which call frame to log, Arguments format and args act as Warningf.
Types ¶
type Level ¶
type Level int32
Level specifies a level of verbosity for V logs. *Level implements flag.Value; the -v flag is of type Level and should be modified only through the flag.Value interface.
type OutputStats ¶
type OutputStats struct {
// contains filtered or unexported fields
}
OutputStats tracks the number of output lines and bytes written.
func (*OutputStats) Bytes ¶
func (s *OutputStats) Bytes() int64
Bytes returns the number of bytes written.
func (*OutputStats) Lines ¶
func (s *OutputStats) Lines() int64
Lines returns the number of lines written.
type Verbose ¶
type Verbose bool
Verbose is a boolean type that implements Infof (like Printf) etc. See the documentation of V for more information.
func V ¶
V reports whether verbosity at the call site is at least the requested level. The returned value is a boolean of type Verbose, which implements Info, Infoln and Infof. These methods will write to the Info log if called. Thus, one may write either
if slog.V(2) { slog.Info("log this") }
or
slog.V(2).Info("log this")
The second form is shorter but the first is cheaper if logging is off because it does not evaluate its arguments.
Whether an individual call to V generates a log record depends on the setting of the -v and --vmodule flags; both are off by default. If the level in the call to V is at least the value of -v, or of -vmodule for the source file containing the call, the V call will log.
func (Verbose) Info ¶
func (v Verbose) Info(args ...interface{})
Info is equivalent to the global Info function, guarded by the value of v. See the documentation of V for usage.
func (Verbose) InfoDepth ¶ added in v1.2.5
InfoDepth is equivalent to the global InfoDepth function, guarded by the value of v. See the documentation of V for usage.
func (Verbose) InfoDepthf ¶ added in v1.2.5
InfoDepthf is equivalent to the global InfoDepthf function, guarded by the value of v. See the documentation of V for usage.
