Appinsight setup without auto instrumentation

Question

Appinsight setup without auto instrumentation

Oussama Dhouioui 20 Microsoft Employee

By default if you have an app service and you set up appinsight for it. Auto instrumentation is enabled.

I'd like to disable it but I don't see in bicep provider any param for appinsight to do that :

https://learn.microsoft.com/en-us/azure/templates/microsoft.insights/components?pivots=deployment-language-bicep ?

Can you please advise?

I wrote my custom telemetry in my app and having auto instrumentation enabled will result in duplicated logs?

I want the infra written with bicep!

Thanks in advance!

Hi Oussama Dhouioui,

Thank you for reaching out to Microsoft Q & A forum.

To disable auto instrumentation in Application Insights when using Bicep, there's no direct property for this in the Bicep schema. However, you can manage this in the following ways:

1.Disable Auto Instrumentation in App Service:

Auto-instrumentation can be disabled by adjusting the APPINSIGHTS INSTRUMENTATIONKEY environment variable in the App Service settings, ensuring that the automatic tracking isn’t enabled.

2.Custom Telemetry:

When using custom telemetry, ensure that automatic tracking for dependencies, requests, and exceptions is disabled within the SDK configuration. This will prevent any duplication of logs.

3.Bicep Template Example:

Below is a sample Bicep template for deploying Application Insights:

resource appInsights 'Microsoft.Insights/components@2020-02-02' = {
  name: 'myAppInsights'
  location: 'East US'
  kind: 'web'
  properties: {
    Application_Type: 'web'
    RetentionInDays: 30
    SamplingPercentage: 100
  }
}

By following these steps, you can configure your Application Insights without enabling auto-instrumentation, ensuring that your custom telemetry remains the primary source for monitoring.
