Why doesn't my app service have the Health checks option?

Question

I'm using one ASE v2 with separate I3 ASPs (one for dev environment and one for staging environment). In our dev ASP our app services have the Health check option available in the portal and we are able to use it. However, in our staging ASP, our app services do not have the Health check option available (it just isn't there in the portal in the Monitoring section). I've verified that I have permissions (contributor role) to view/manage Health checks. And our devops admin with full permissions also doesn't see the Health check option either.

I did read in the Health check docs that ASE v2 doesn't support Health checks, but that doesn't explain why we can use Health checks on some of our app services, but not others. It doesn't make sense that we would even see the Health check option in the portal if they aren't supported by ASE v2.

And yes, I know ASE v2 is going away this year and that we need to upgrade. That will be happening later this year.

Any ideas why we don't see Health checks on some of our app services? Or how to make them show up?

Answer 1

Hi @Rafe Kemmis , I understand that you have several App Services using ASE v2. You are trying to enable Health checks but some of your App Service plans do not have Health check option available.

I think you referred to this document about Health check not supported on ASE v2:

Does Health check work on App Service Environments? Yes, health check is available for the App Service Environment v3, but not for versions 1 or 2. If you are using the older versions of the App Service Environment, you can use the migration feature to migrate your App Service Environment to version 3.

Could it be that your dev/staging environment uses Free or Shared App Service Plan? Or has it been upgraded to ASE v3? Does your ASE use ILB (Internal Load Balancer) or ELB (External Load Balancer)?
