Azure Monitor
An Azure service that is used to collect, analyze, and act on telemetry data from Azure and on-premises environments.
I see a role in Application Insights called: unknown_service:Microsoft.Azure.WebJobs.Script.WebHost

Hi
As I wrote in the title I see something called "unknown_service:Microsoft.Azure.WebJobs.Script.WebHost" is connected to my application insights. I have already two services (1 regular app service and 1 azure function service) wired up to this app insights instance. At first glance, it looks like unknown_service:Microsoft.Azure.WebJobs.Script.WebHost stems the functions service, but I'm not sure about that.
What can I do about it?

Please provide answers for below questions to investigate the issue further.
- Which Azure resources are currently sending telemetry to this Application Insights instance?
- Does the unknown_service:Microsoft.Azure.WebJobs.Script.WebHost role appear only when the Azure Function App is running?
- In the Application Insights Logs, do the events associated with this role show distinct values for
cloud_RoleName,cloud_RoleInstance, andsdkVersionthat map to a specific Function App? - Are both the App Service and the Function App configured to send telemetry to this same Application Insights resource?
Please share screenshots (or details) of the Application Insights settings for both resources.
