In Golang how you guys manage to write logs into multiple file base on the package name.
For example in my current app, I am trying to collect multiple hardware stats from different packages called Netapp, IBM etc but under the same application. So, I would like to write logs from those package in separate folder like /var/log/myapp/netapp.log and /var/log/myapp/ibm.log?
Any pointer or clue would be very helpful ?
Thanks James
One approach you could take is to implement the Observer pattern. It's a great approach when you need to make several things happen with the same input/event. In your case, logging the same input to different logs. You can find more information here.
In a situation you described and following this example, you can do following things:
Observer interface by putting your logging code for each logging implementation in OnNotify method.Create an instance of eventNotifier and register all your logging implementations with eventNotifier.Register method. Something like:
notifier := eventNotifier{
observers: map[Observer]struct{}{},
}
notifier.Register(netAppLogger)
notifier.Register(ibmLogger)
Use eventNotifier.Notify whenever and wherever you need to do logging and it will use all registered logging implementations.
