How to Log Exceptions to Azure application logs

Question

I have a ASP.Net MVC Web Application hosted in Azure Web Service. I need to log Exceptions to Application Log.

Later I want to check and review what kind of exceptions happened.

How can I do it?

Answer 1

If by exceptions you mean those caught inside a try-catch then you could do;

1. Follow the steps mentioned here, you need to toggle this setting on your Azure web app;

   Your App > App Service Logs > Turn On Application Logging (FileSystem)

2. Then use the code below; Trace.Information(), Trace.Warning(), Trace.Error()

using System.Diagnostics;

public ActionResult sample(){
   try{
      Trace.Information("Hello World!");
   }catch(exception e){
      Trace.Error(e.Message);
   }
}
