Track System.Diagnostics.Trace logs in Azure portal

Question

In my web application, I use

System.Diagnostics.Trace.WriteLine(...);

for diagnostics. The application is published to an Azure deployment slot. I am wondering where I can find these logs in the Azure Portal (or Visual Studio's cloud explorer).

Do you not have to configure the location of these logs in your web.config? – Renowned

Answer 1

You first need to activate the Application Logging:

1. Go to your Web App.
2. Go to Monitoring / App Service logs.
3. Enable Application Logging and configure it.

Where is Application logging now (the menu and options are all very different now, and search does not show that name) – Sestina
