title: Use Event Log (Write in Event Viewer) in Azure
body: <p>My website, written in ASP.NET and i used EventLog to write logs into the event viewer. It is already been running in the production (OS: Windows Server 2012 R2) and no problems encountered upon logging some errors. I am now planning to migrate the server to Azure - App Services. I wonder if my code in logging the errors would still work after moving to Azure - App Services?? If yes then how do i view the error that have been logged by my website?? I cannot see Event Viewer in the Azure - App Services. If no then what is the simplest and fastest alternate way to replace my code in logging the errors??</p>
  
  <p>Here is my code:</p>
  
  <pre><code>public static void LogEventLog(string message, EventLogEntryType logType)
      {
          string source = AppConfig.ErrorEventViewerSource;
  
          // Since we can't prevent the app from terminating, log this to the event log. 
          CreateEventSource(source);
  
          // Create an EventLog instance and assign its source.
          EventLog myLog = new EventLog();
          myLog.Source = source;
          myLog.WriteEntry(message, logType);
  
      }
  
  
  
      public static void CreateEventSource(string source)
      {
          if (!EventLog.SourceExists(source))
          {
              EventLog.CreateEventSource(source, "Application");
          }
      }
  </code></pre>
