Cannot find entries in Logs

Question

I'm trying to find log entries from my application in the portal. This is a .net core 3 web application. Below is the setup in my code:

This is how I am calling the logging:

I see the logging appear in the Log Stream:

I need to view this information in the Logs using a query. I've set up Diagnostic settings:

Looking in the logs I've changed the scope to the application, the blob storage, and the log analytics work space I set up. I'm not able to find the message that appears in the Log Stream anywhere.

Does anyone have any ideas about what I'm missing?

Hi @Kyrian Willis ,

I do want to make the distinction that AzureWebAppDiagnostics doesn't gain you Azure Monitor logs support. It, depending on configuration, writes to either a text file or blob storage; see https://learn.microsoft.com/en-US/dotnet/core/extensions/logging-providers#azure-app-service. You can configure AzureFileLoggerOptions or AzureBlobLoggerOptions but by default, configs are pulled from your app.settings.json, see https://github.com/dotnet/aspnetcore/blob/c925f99cddac0df90ed0bc4a07ecda6b054a0b02/src/Logging.AzureAppServices/src/AzureAppServicesLoggerFactoryExtensions.cs#L32.

Having said that, unfortunately, AppServiceAppLogs doesn't yet support .NET Core, here are the currently supported types. I do know AppServiceConsoleLogs support for .NET Core is currently being worked on.
