logging

Simple logging package with direct file and other appenders

Goal of the package

• simple logging package to persist every log to file
• flexible and easy file rotation configurations
• wrap commonly used logging package(currently logrus) for providing general api

Get started

1. Create LoggingManager for file persistent

manager, err := logging.NewLoggerManager("logs/fim", 1, 1*1024*1024, 2, logrus.TraceLevel, true, true)

Parameters:

• log file path+prefix
• max days
• max file size
• max file per day
• log level
• enable caller info
• enable print log to console

2. Get Logger from LoggingManager

logger := manager.GetLogger("demoLogger001")

Parameter:

• Logger name

3. Use Logger

type Logger interface {
	Trace(objects ...interface{})
	TraceF(format string, args ...interface{})
	IsTraceEnabled() bool

	Debug(objects ...interface{})
	DebugF(format string, args ...interface{})
	IsDebugEnabled() bool

	Info(objects ...interface{})
	InfoF(format string, args ...interface{})
	IsInfoEnabled() bool

	Warn(objects ...interface{})
	WarnF(format string, args ...interface{})
	IsWarnEnabled() bool

	Error(objects ...interface{})
	ErrorF(format string, args ...interface{})
	IsErrorEnabled() bool
}
