------------------------------------
global logger model
==================
```
func main() {
flag.Parse()
defer elog.Flush()
for i := 0; i < 100; i++ {
go func() {
elog.Info("hello", "world")
}()
}
time.Sleep(time.Second)
}
```
./example_elog -logToStderr -logLevel=INFO -logFlushTime=3 -logPath=./
LoggerHandler model
===================
```
type TestLogHandler struct {
}
func (lh *TestLogHandler) Write(data []byte) (int, error) {
return os.Stderr.Write(data)
}
func (lh *TestLogHandler) Flush() {
os.Stderr.Write([]byte("flush\n"))
}
func main() {
writer := &TestLogHandler{}
log := elog.NewEasyLogger("INFO", false, 3, writer)
defer log.Flush()
log.Info("hello", "world")
}
```
elog config
=================
-logFlushTime int
log flush time interval,default 3 seconds (default 3)
-logLevel string

* 2.rotate files max num is 10
elog high performance
======================
* log to cache buffer then flush to file
* cache buffer size is 1M
* default flush time 3 seconds,-logFlushTime can change flush time interval
* if want close log outputing,-logLevel=NONE can close log outputing
