在 Azure 函数应用程序中为 Application Insights 配置云角色名称

Question

I would like to set the cloud_rolename of the telemetry sent from my Azure Function App (v2) that is sent to application insights.

The AI configuration in my host.json looks like this:

 "applicationInsights": {
          "sampling": {
            "isEnabled": true,
            "maxTelemetryItemsPerSecond" : 1
          }
        }

I have been unable to find any documentation on where to set cloud rolename in function apps. How should I go about this?

You should be able to do this by registering a custom TelemetryInitializer . See here: https://github.com/Microsoft/ApplicationInsights-aspnetcore/issues/759#issuecomment-426687852 .

We currently set that role name in an initializer today here: https://github.com/Azure/azure-webjobs-sdk/blob/dev/src/Microsoft.Azure.WebJobs.Logging.ApplicationInsights/Initializers/WebJobsRoleEnvironmentTelmetryInitializer.cs .

Can I ask what your scenario is that you'd want to override it?
