Hello. I've installed osquery on one my host, i'm seeing tracking from the host to fleet host but fleet is not enrolling it. Any way to debug it?

Check out https://github.com/fleetdm/fleet/blob/master/docs/2-Deployment/FAQ.md#why-arent-my-osquery-agents-connecting-to-fleet

I build my clients with kolide launcher, can i set those osquery flags on build?

Ah, I'm not sure. Maybe there's a verbose or debug flag?

Yeah, i can set up those flags with kolide launcher. But how i debug it? Seeing fleet logs?

Typically debugging enrollment requires access to the host since we can't get the logs into Fleet until the host successfully enrolls
