Determine puppet agents using capsule as puppet master

Is there a way to query either satellite via hammer CLI or the puppet master itself (i.e. the capsule) to determine which hosts are using that capsule as a puppet master?

We have 13 capsules all setup as puppet masters and have static configuration pointing to them, but we have 3,000 hosts and it would be easier to query the master or satellite and sort a CSV to determine the lists for when we migrate to 6.2.8 from 6.1.7

Thanks
