Application Logging in Azure Container Apps

Azure Container Apps provides two types of application logging categories:

You can view the log streams in near real-time in the Azure portal or CLI. For more options to store and monitor your logs, see Logging options.

Container console Logs

Container Apps captures the stdout and stderr output streams from your application containers and displays them as console logs. When you implement logging in your application, you can troubleshoot problems and monitor the health of your app.

  • Successfully created dapr component
