also, I'm aware of the /metrics page and I read somewhere that it is 'suitable for prometheus ingestion' but I can't find that page any more. Does anyone know where the /metrics endpoint is documented?

It’s accessible at

/metrics

on the same port as the Fleet UI/API

yes, exactly. I can browse it just fine. I just recall reading that the output was suitable for prometheus ingestion and I was wondering where i found that as I assume that wherever that is might have some additional context into these metrics. 🙂

You may have found that information here in the docs: https://github.com/fleetdm/fleet/blob/master/docs/infrastructure/faq.md#how-do-i-monitor-a-fleet-server However, the docs provide no more information than you’ve already mentioned.

ah, yes. I knew I saw it somewhere. thanks. That would be great if you can document more details.
