Types

type Logger

type Logger struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Logger encapsulates the logging device that is used to emit logs and as a receiver that has the logging methods

func NewErrLogger

func NewErrLogger(component string) (log *Logger)

NewErrLogger can be used to instantiate a wrapper logger with a module label with output going stderr

func NewLogger

func NewLogger(component string) (log *Logger)

NewLogger can be used to instantiate a wrapper logger with a module label with output going stdout

func (*Logger) Debug

func (l *Logger) Debug(msg string, args ...interface{})

Debug is a method for output of debugging level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) Error

func (l *Logger) Error(msg string, args ...interface{}) error

Error is a method for output of error level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) Fatal

func (l *Logger) Fatal(msg string, args ...interface{})

Fatal is a method for output of fatal level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) HostName

func (l *Logger) HostName(hostName string) (log *Logger)

HostName is used to add an optional host name to messages, if empty then the host name will not be output

func (*Logger) IncludeStack

func (l *Logger) IncludeStack(included bool) (log *Logger)

IncludeStack is used to enable a small function call stack to be included with messages

func (*Logger) Info

func (l *Logger) Info(msg string, args ...interface{})

Info is a method for output of informational level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) IsDebug

func (l *Logger) IsDebug() bool

IsDebug returns true in the event that the theshold logging level allows for debugging messages to appear in the output

func (*Logger) IsInfo

func (l *Logger) IsInfo() bool

IsInfo returns true in the event that the theshold logging level allows for informational messages to appear in the output

func (*Logger) IsTrace

func (l *Logger) IsTrace() bool

IsTrace returns true in the event that the theshold logging level allows for trace messages to appear in the output

func (*Logger) IsWarn

func (l *Logger) IsWarn() bool

IsWarn returns true in the event that the theshold logging level allows for warning messages to appear in the output

func (*Logger) Label

func (l *Logger) Label(key string, value string)

func (*Logger) Log

func (l *Logger) Log(level int, msg string, args []interface{})

Log is a method for output of parameterized level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) SetLevel

func (l *Logger) SetLevel(lvl int)

SetLevel can be used to set the threshold for the level of messages that will be output by the logger

func (*Logger) Trace

func (l *Logger) Trace(msg string, args ...interface{})

Trace is a method for output of trace level messages with a varargs style list of parameters that is formatted as label and then the value in a single list

func (*Logger) Warn

func (l *Logger) Warn(msg string, args ...interface{}) error

Warn is a method for output of warning level messages with a varargs style list of parameters that is formatted as label and then the value in a single list
