Maybe you can explain the problem you're trying to solve.

You're not just trying to find the VMs which are DEAs, you need to be able
to do this constantly and programmatically. What's the actual overall goal
here, why do you need to do this?

Thanks,
Amit

I believe you could use the BOSH API:

I hadnt considered that. I see that there are now docs for the BOSH api,
however is the BOSH api suited to concurrent access by multiple processes?
We are writing a component that will need to frequently validate that a
particular machine is a DEA.

What about with BOSH?

I am trying to enumerate all the ways I could identify all the DEA's in
a CF cluster in an IAAS agnostic way (e.g. not querying Openstack to read
metadata on the VM's that list the job type).

I think the only reliable way is to listen on NATS and look for the DEA
advertisement messages. Am I correct or is there a method I am missing (I'd
rather call and API rather than subscribe to NATS)?
