Azure - monitoring apps (oAuth)?

Is it possible to monitor apps in Azure or Azure certificates, specially we are building an oAuth one for ServiceNow.

Would this app be picked up when the resources are found during discovery?

We have Azure configured in our environment and I can see the resource groups setup as hosts.
I guess my question is if an app is created within a resource group will it appear under that resource group host in checkmk for monitoring?

What I am looking for here actually is how to monitor SAML certificate expiry in Azure and also app certificates and client secrets expiration. Is this possible?
