Functions ¶
func Close ¶
func Close()
Close informs the configured loggers that they are being closed and should cleanup (for instance, flushing any queued log messages)
func Critical ¶
func Critical(msg string)
Critical sends a message to the logger object to record critical level statements (these indicate conditions that should never occur and might cause a failure/crash of the executing program or unexpected outcome from the requested action).
func Criticalf ¶
func Criticalf(format string, params ...interface{})
Criticalf formats a message before sending it to the logger object to record critical level statements (these indicate conditions that should never occur and might cause a failure/crash of the executing program or unexpected outcome from the requested action).
func Debug ¶
func Debug(msg string)
Debug sends a message to the logger object to record debug/trace level statements
func Debugf ¶
func Debugf(format string, params ...interface{})
Debugf formats a message before sending it to the logger object to record debug/trace level statements
func Error ¶
func Error(msg string)
Error sends a message to the logger object to record error level statements (these indicate conditions that should not occur and may indicate a failure in performing the requested action).
func Errorf ¶
func Errorf(format string, params ...interface{})
Errorf formats a message before sending it to the logger object to record error level statements (these indicate conditions that should not occur and may indicate a failure in performing the requested action).
func Fatal ¶
func Fatal(msg string)
Fatal sends a CRITICAL message to the logger object and then exits. NOTE: This call should not be made in packages that are meant to serve as libraries for other developers.
func Fatalf ¶
func Fatalf(format string, params ...interface{})
Fatalf sends a formatted CRITICAL message to the logger object and then exits. NOTE: This call should not be made in packages that are meant to serve as libraries for other developers.
func Info ¶
func Info(msg string)
Info sends a message to the logger object to record informational level statements (these should be statements that can normally be logged without causing performance issues).
func Infof ¶
func Infof(format string, params ...interface{})
Infof formats a message before sending it to the logger object to record informational level statements (there should be statements that can normally be logged without causing performance issues).
func Panic ¶
func Panic(msg string)
Panic sends a CRITICAL message to the logger object and then calls panic. NOTE: This call should not be made in packages that are meant to serve as libraries for other developers.
func Panicf ¶
func Panicf(format string, params ...interface{})
Panicf sends a formatted CRITICAL message to the logger object and then calls panic. NOTE: This call should not be made in packages that are meant to serve as libraries for other developers.
func RegisterLogger ¶
RegisterLogger must be called to map a concrete logger object with each log level.
func SetLogLevel ¶
func SetLogLevel(level LogLevel)
SetLogLevel sets the current package-level filtering
Types ¶
type LogLevel ¶
type LogLevel int
LogLevel is used for global (package-level) filtering of log messages based on their priority (this filtering is applied before all other filtering which might be provided by the concrete logger).
func GetLogLevel ¶
func GetLogLevel() LogLevel
GetLogLevel returns the current package-level filtering
func NewLogLevel ¶
NewLogLevel converts a string to a log level.
func (LogLevel) MarshalJSON ¶
MarshalJSON converts a LogLevel to a quoted string for JSON output.
func (*LogLevel) UnmarshalJSON ¶
type Logger ¶
type Logger interface {
Debug(string)
Debugf(string, ...interface{})
Info(string)
Infof(string, ...interface{})
Warning(string)
Warningf(string, ...interface{})
Error(string)
Errorf(string, ...interface{})
Critical(string)
Criticalf(string, ...interface{})
GetLogLevel() syslog.Priority
SetLogLevel(syslog.Priority)
Close()
}
Generic interface that all concrete loggers must implement. Using this interface directly isolates user code from a particular logger implementation.
