hi everyone, how can i check if fleet server is connected to the load balancer?

Hi @peanut butter, let me check with the team and I'll get back to you. We are discussing something similar in https://osquery.slack.com/archives/C01DXJL16D8/p1652641454717579.

Note that the load balancer connects to Fleet, not the other way around. You need to make sure your load balancer is configured to be aware of each running Fleet server so that connections can be routed to them.

Fleet also has a

/healthz

endpoint that can be used in the health-checking portion of your load balancer for it to determine if it can use a particular Fleet backend. Almost any modern load balancer will support this. See https://fleetdm.com/docs/using-fleet/monitoring-fleet#health-checks for what the responses are for healthy vs unhealthy.

Reading between the lines. Have you deployed fleet and are unsure if clients are being blocked by a corporate firewall or load balancer ?
