Well, the initial thing to check is the operating status. It will
indicate if the members are testing healthy or failing the health
checks.

If you want to provide the HAProxy connection logs, you can enable
Amphora tenant log offloading[1]. This will allow you to forward the
haproxy logs (stamped with the project ID) via syslog protocol. You
can then use that to expose them to your users.

Finally, users can enable a Prometheus exporter on their load balancers[2].
