[QUERY] How to stop function log spam in console app for .NET 6 / V4 functions

Library name and version

Azure.Messaging.ServiceBus 7.5.1

Query/Question

Previous version (NET Core 3.1), we could watch the consoles and follow app behavior, now almost all of the console output is functionally spam.

I want to filter out

Which occur at least 100 per function and

which is less frequent but still relatively significant pollution.

I’ve tried modifying the host.json from Default “debug”, to only display information

  "logging": {
    "logLevel": {
      "Default": "Information",
      "System": "Information",
      "Microsoft": "Warning"
    }
  }

and it didn’t reduce logging, and I’m afraid that if we reduce the logging level further that we’re just going to be obfuscating the information we want, because we used to be able to see when a function picked up a message and then when it marked it as complete, as well as internal logging data.

Environment

.NET 6 VS 2022

Hi @Prinsn. Thank you for reaching out. To change the log detail that you’re seeing for Service Bus or other Azure SDK packages, you’ll need to configure their levels independently. For example, if you wanted to restrict Service Bus to just warnings and errors, you’d use something similar to:

"Logging": {
  "LogLevel": {
    "Default": "Information",
    "System": "Information",
    "Microsoft": "Warning"
    "Azure.Messaging.ServiceBus": "Warning"
  }
}

There’s a bit more context in the discussion on #25865, if you’re interested.

You and Josh are really doing serious work with this repo.
