Hi,

I’m trying to use the API for two things:

1. Get the old behavior of `#each` (show all services, not just active ones) for Prometheus (you don’t want nodes to be removed from monitoring / alerting when the supervisor stops on a node)
2. Get some information to feed into Prometheus (hopefully this can go back in-core at some stage)

For the first one I get all the `.service.list.` entries and then remove all the `.departure.list.departure` entries. This works well.

For the second one I’m trying to identify the following:

- total number of supervisors running a service (the service appears in `hab sup status`)

I can’t for the life of me seem to find a way of identifying this.

I can get the list of all services, and I can count the supervisor ids which are listed - but I can’t find a way of identifying supervisors which are **no longer** running the service so I can exclude them.

Am I just looking in the wrong place??

Actually not working ☹

Would you expect to be able to locate running services from `/census` or `/butterfly` ?

Does the `/services` endpoint have the information you need?

It does, but then I have to contact all the supervisors individually.

I was under the assumption service state changed was gossiped when I wrote this - I was wrong!
