Service nesting and topology mapping

I would like to see that services can be be nested and relationship based on the nesting with alert settings on the relationship.

For instance we have products that contain multiple components now each is monitored and using group strucure we can kind of do a root cause.

But it we can use services with maps and build relationships between them we could for instance see that a website goes down because on a sql server the logdisk fails.

the service than from a user perpective is the website. But from tech perspective it is the whole chain. If we can use services to include the websitecheck, the webserver, the database, the hardware stack each connected using a service depending on the other service shown on a map would directly point you to the root cause.

Guess here LM lacks in my opinion.
