Relay Exposes Usage Statistics over some (JS?) Api

[peter-sanderson]

Something along the lines:

const relay = await createNodeJsRelay(deps)({...})

const usageDtata = relay.getUsageDataForOwner(ownerId)

Should ideally expose prometheus compatible metrics on private metrics port which can be scraped with prometheus.

@vdovhanych I think using prometheus is our deal, Evolu Relay shall offer method to get data, precise formatting/technology is up to us.

[vdovhanych]

Yes but it should expose the metrics in a way we can scrape them and i would vote for prometheus compatbile metrics endpoint.
