How to do VCA functionality verification

I am in the process of upgrading all VCA to latest version 7.3.5.0 on all servers accross the organization.

Is there an easy way to verify if the installations are working?

I can query SCCM and verify the version installed. But how can I assure it actually works and loads the data properly from the repository?

i.e. for a small number of servers, I can just load the Version control page and check if the agent is loading any data. But I need to be able to do this for 30-50 servers at a time.

Any suggestions?
