Overview ¶
Package logging implements log library for other applications. It provides functions Debug, Info, Warning, Error, Critical, and formatting version Logf.
Example:
logger := logging.SimpleLogger("main")
logger.SetLevel(logging.WARNING)
logger.Error("test for error")
logger.Warning("test for warning", "second parameter")
logger.Debug("test for debug")

Functions ¶
func GetLevelName ¶
GetLevelName lets users be able to get level name from level value.
Types ¶
type Level ¶
type Level int32
Level is the type of level.
const ( CRITICAL Level = 50 FATAL Level = CRITICAL ERROR Level = 40 WARNING Level = 30 WARN Level = WARNING INFO Level = 20 DEBUG Level = 10 NOTSET Level = 0 )
Values of level
func GetLevelValue ¶
GetLevelValue lets users be able to get level value from level name.
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
Logger is the logging struct.
func BasicLogger ¶
BasicLogger creates a new logger with basic configuration.
func ConfigLogger ¶
ConfigLogger creates a new logger from a configuration file
func CustomizedLogger ¶
func CustomizedLogger(name string, level Level, format string, timeFormat string, out io.Writer, sync bool, queueSize int, requestSize int, bufferSize int, timeInterval time.Duration) (*Logger, error)
CustomizedLogger creates a new logger with all configurations customized (in addition to WriterLogger).
func FileLogger ¶
func FileLogger(name string, level Level, format string, timeFormat string, file string, sync bool) (*Logger, error)
FileLogger creates a new logger with file output.
func RichLogger ¶
RichLogger creates a new logger with simple configuration.
func SimpleLogger ¶
SimpleLogger creates a new logger with simple configuration.
func WriterLogger ¶
func WriterLogger(name string, level Level, format string, timeFormat string, out io.Writer, sync bool) (*Logger, error)
WriterLogger creates a new logger with a writer
func (*Logger) Destroy ¶
func (logger *Logger) Destroy()
Destroy sends quit signal to watcher and releases all the resources.
func (*Logger) Log ¶
Log receives log request from the client. The request includes a set of variables.
func (*Logger) Logf ¶
Logf receives log request from the client. The request has a string parameter to describe the format of output.
