logger日志架构

logger日志,内置了2个缓存container,所有的日志输入时,会把日志中的数据先存入container1 中,待container1存满之后,会将container1释放并输出,并且,接下来的日志会放入container2 中,如此循环

• 打印文本日志

  • 输出格式是文本:

      cfg := logger.NewConfig(logger.ToConsole)
      cfg.SetCententType(logger.ToConsole, logger.FormatText)
      
      2016/05/23 15:51:19 [example.go:14] <example>  Debug: test for log 1
      2016/05/23 15:51:19 [example.go:14] <example>  Debug: test for log 2
      2016/05/23 15:51:19 [example.go:14] <example>  Debug: test for log 3
    

  • 输出格式是json:

      cfg := logger.NewConfig(DefaultLog.ToConsole)
      cfg.SetCententType(logger.ToConsole, logger.FormatJson)
      
      {"log_id":"","log_level":"Debug","module":"example","time":"2016/05/23 16:12:41","filename":"example.go","line":14,"remark":"test for log 1"}
      {"log_id":"","log_level":"Debug","module":"example","time":"2016/05/23 16:12:42","filename":"example.go","line":14,"remark":"test for log 2"}
      {"log_id":"","log_level":"Debug","module":"example","time":"2016/05/23 16:12:42","filename":"example.go","line":14,"remark":"test for log 3"}
    

  • 附加字段:

      DefaultLog.WithFields(logger.Fields{
      			"foo":"test1",
      			"bar":"test2",
      }).Debug("test for log %d", i)
    

• Usage:

    package main
    
    import (
    	"time"
    
    	"github.com/go-wyvern/logger"
    )
    
    var DefaultLog *logger.Logger
    
    func main() {
    	var i int
    	for {
    		i++
    		DefaultLog.WithFields(logger.Fields{
    			"foo":"test1",
    			"bar":"test2",
    		}).Debug("test for log %d", i)
    		time.Sleep(200 * time.Millisecond)
    	}
    }
    
    func init() {
    	cfg := logger.NewConfig(logger.ToConsole)
    	cfg.SetCacheSize(2048) //可设置,也可以不设置,默认1024
    	cfg.SetCententType(logger.ToConsole, logger.FormatJson)
    	cfg.SetLevel(logger.Debug)
    	DefaultLog = logger.New(cfg)
    	DefaultLog.SetModule("example")
    	//DefaultLog.Cache.CacheMonitor()//监控缓存 可开可不开 不开注释即可
    }
