Logs not appearing in Azure portal for Function using Logback, but visible with ExecutionContext

Question

I'm experiencing an issue with logging in Azure Functions (Java). When I use ExecutionContext.getLogger(), my logs appear in both the Azure portal and the log stream. However, when I use Logback for logging, I can see the logs in the log stream, but they do not appear in the Azure portal's logs.

Here’s a summary of my setup:

• Azure Functions with Java runtime.
• Logback is configured correctly, and I see the logs in the log stream.
• Logs written using ExecutionContext.getLogger() are visible in both the log stream and Azure portal, but the same is not true for Logback logs.

Is there a specific configuration required to ensure Logback logs are also visible in the Azure portal? Any insights or suggestions would be greatly appreciated!
