How to convert appsettings.json to (bicep) parameters.json file for logging?

[siegfried01]

I'm deploying a webapp & appconfig using bicep file and bicep parameters.json file.

I want to specify "trace" level for all the logging providers in the sample appsettings.json file here: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-7.0#configure-logging

Here is a fragment of my parameters.json file .

{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"aadb2cConfig" : {
"value": {
"Instance": "https://xxxxxxxxxxxxx.b2clogin.com",
"ClientId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"Domain": "xxxxxxxxxxxxxx.onmicrosoft.com",
"SignedOutCallbackPath": "/signout/B2C_1_susi",
"SignUpSignInPolicyId": "b2c_1_susi",
"ResetPasswordPolicyId": "b2c_1_reset",
"EditProfilePolicyId": "b2c_1_edit_profile"
}
},

Here is a fragment from my bicep file:

@description('Azure AD B2C Configuration [{key:"", value:""}]')
param aadb2cConfig object
resource config 'Microsoft.AppConfiguration/configurationStores@2020-06-01' = {
  name: '${name}-config'
  location: location
  sku: {
    name: configSku
  }
  resource Aadb2cConfigValues 'keyValues@2020-07-01-preview' = [for item in items(aadb2cConfig): {
    name: 'AzureAdB2C:${item.key}'
    properties: {
      value: item.value
    }
  }]
}

This is working! yahoo!

I'm not clear on how to enhance my parameters.json file and my bicep file to include the log settings since the nesting of logging objects gets kinda deep as exemplfied in this appsettings.json file:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  }
}

Can someone point me to an example I could follow?

Please also include the nested for loop in the bicep file that would stuff this into an azure AppConfig so that the C# Visual Studio code for a Web App would automagically grab it after having specified the connection string to the AppConfig.

Also, it seems like there should be a nice little tool to convert the appsettings.json file to the parameters.json file. Maybe this is a job for emacs/elisp? Hopefully there is a better way! I wonder if there is an VSCode or Visual Studio extension?

This appsettings.json file could be tedious with out a tool:

{
  "Logging": {
    "LogLevel": { // No provider, LogLevel applies to all the enabled providers.
      "Default": "Error",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Warning"
    },
    "Debug": { // Debug provider.
      "LogLevel": {
        "Default": "Information" // Overrides preceding LogLevel:Default setting.
      }
    },
    "Console": {
      "IncludeScopes": true,
      "LogLevel": {
        "Microsoft.AspNetCore.Mvc.Razor.Internal": "Warning",
        "Microsoft.AspNetCore.Mvc.Razor.Razor": "Debug",
        "Microsoft.AspNetCore.Mvc.Razor": "Error",
        "Default": "Information"
      }
    },
    "EventSource": {
      "LogLevel": {
        "Microsoft": "Information"
      }
    },
    "EventLog": {
      "LogLevel": {
        "Microsoft": "Information"
      }
    },
    "AzureAppServicesFile": {
      "IncludeScopes": true,
      "LogLevel": {
        "Default": "Warning"
      }
    },
    "AzureAppServicesBlob": {
      "IncludeScopes": true,
      "LogLevel": {
        "Microsoft": "Information"
      }
    },
    "ApplicationInsights": {
      "LogLevel": {
        "Default": "Information"
      }
    }
  }
}

Add your logging as a settings object notation to an app config object. Assuming dotnet, it would look something like this:

resource appSettings 'Microsoft.Web/sites/config@2021-02-01' = {
  name: '${appName}/appsettings'
  properties: {
    // 'APPINSIGHTS_INSTRUMENTATIONKEY': instrumentationKey
    // 'ApplicationInsights:InstrumentationKey': instrumentationKey
    'Logging:ApplicationInsights:Enabled': 'true'
    'Logging:ApplicationInsights:LogLevel': 'Information'
    'Logging:LogLevel:Default' : 'Error'
    'Logging.LogLevel:Microsoft' : 'Warning'
  }
}

@siegfried01 please confirm if @RyanHill-MSFT solution works for your needs?

Let's assume it works! Since I just discovered my azure function app deployment problems are being caused by a missing storage account I have not had a chance to try it out yet. But before I mark it as an answer, please clarify the difference logging features in that link above.

Specifically I wanted to try out the "Console", "EventSource", "EventLog", "AzureAPISericesFile" clauses to learn how they work.

Are all of these appropriate & applicable logging features for webapps and function apps can be applied with the same syntax demonstrated by Ryan in the above fragment?
