Logging customization

Besides the logging with the default logger from the log package, the standard library also provides a way to create the custom logger, according to the needs of the application or package. This recipe will give a brief insight on how to create one.

How to do it...

1. Open the console and create the folder chapter11/recipe01.
2. Navigate to the directory.
3. Create the file logging.go with the following content:

        package main

        import (
          "log"
          "os"
        )

        func main() {
          custLogger := log.New(os.Stdout, "custom1: ",
                                log.Ldate|log.Ltime)
          custLogger.Println("Hello I'm customized")
