Prometheus service

[Seena Fallah]

Hi all.
I have upgraded to HAProxy 2.0.13 and enabled Prometheus service on it. In
previous version (1.8.8) I used haproxy_exporter
<https://github.com/prometheus/haproxy_exporter> and I
have haproxy_server_check_duration_milliseconds and new_session_rate for
each server but in HAProxy v2.0.13 Prometheus service I don't see these
metrics.
How can I have them?
