I recently upgraded our Azure Functions app from .NET 6 to .NET 8. Some strange behavior is occuring where I’m unable to see Information (or below) level logs. The settings pertaining to logs are the same.

Code:

Logger?.LogError("Test if we can log error");
Logger?.LogWarning("Test if we can log warning");
Logger?.LogInformation("Test if we can log info");
Logger?.LogDebug("Test if we can log debug");

Logs:

[2024-05-30T10:24:45.823Z] Test if we can log error
[2024-05-30T10:24:45.824Z] Test if we can log warning
.. that's it

Logging obviously works because I can see Error and Warning log levels. My host.json:

{
  "version": "2.0",
  "logging": {
    "logLevel": {
      "AlarmFunctions.Functions": "Debug",
      "DataLayer": "Debug",
      "ServiceLayer": "Debug",
      "Function": "Warning",
      "default": "Warning"
    },
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Trace;Request"
      },
      "LogLevel": {
        "Default": "Warning"
      }
    }
  },
  "extensions": {
    "serviceBus": {
      "maxMessageBatchSize": 5
    },
    "durableTask": {
      "storageProvider": {
        "maxQueuePollingInterval": "00:00:01"
      }
    }
  }
}

Important to note is that logLevel in host.json does not apply anymore. Above provided logging code is located in namespace AlarmFunctions.Functions.SomeClassName but changing loglevel to "AlarmFunctions.Functions": "Error" still makes the warning log show up.

Am i missing something?

Thanks
