Monitor Azure Functions in production

- [Instructor] Because of the stateless nature…of Azure functions,…it might be tricky to get…good analytics and see how our code…is behaving when deployed.…In this video, we will see what our options are.…Although I did not mention it explicitly,…you might have noticed that a TraceWriter object…is injected into the Azure function's run method.…This is built into the Azure function's run time…and provides you with basic logging out of the box.…You can also use the ILogger interface's log provider.…With the ILogger interface, you can have structured logs,…and divide the log messages up in more…logical group units.…

Both the TraceWriter and ILogger log providers,…will show up in application insights,…which we will see in a minute.…To use the ILogger interface, simply change…the TraceWriter parameter into a ILogger parameter.…The Azure function run time will inject…a concrete implementation of the ILogger interface…at run time.…You can provide your own implementation…to be able to use your favorite log framework.…Another advantage of using the ILogger interface…
