问题
I am using Azure Web App Application Logging, and I followed the online tutorial, and made the following setup:
I get an exception and in my catch block I have the following code:
Trace.TraceError("abc");
Trace.TraceInformation("abc");
Trace.TraceWarning("abc");
Trace.WriteLine("abc");
Console.WriteLine("abc");
In the logs I get this:

How can I get my application logging to show up?
回答1:
According to the log format of error message you provided, I assumed that the log file you provided is belongs to Web Server Logs ( under /LogFiles/http/RawLogs) which formatted using W3W Logging. Based on your configuration, you have both enabled file system and blob storage for Application Logging. You could retrieve your application logs as follows:
Application Logging (Filesystem)
For a simple way, you could leverage KUDU, click "Debug console > CMD" and cd LogFiles\Application, then you could retrieve your logs as follows:
Application Logging (Blob)
You could leverage Microsoft Azure Storage Explorer to retrieve your logs as follows:
