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?


Hi,

check_duration is not exported but it could be. But if so, it would be exported 
in second using a float representation. So the metric name would be 
haproxy_server_check_duration_seconds. About new_session_rate, I guess you mean 
current_session_rate. This one was removed on purpose. It can be deduced from 
sessions_total metric using Prometheus rate() function.

After ~20 hours of running Prometheus scraper with ss-20190706 the ssl handshake
errors are gone. From my point of view works the Prometheus exporter now.

Hi.

I use HAP 2.0.1 with haproxy service with my image.
After some times (~several hours) the ssl handshake stops working for the https
frontend which offers the prom service.

The config is mainly the same as showing at the blog post

https://www.me2digital.com/blog/2019/05/haproxy-sni-routing/

I have just added this line.

```
http-request use-service prometheus-exporter if { path /mymetrics }
```

This is the prometheus config snipplet.

```
   - job_name: 'me2d-prom'
 metrics_path: '/mymetrics'
 scheme: 'https'

 static_configs:
 - targets: ['cloud.domain']

```

The lines in the logs does not show too much

```
:::85.10.XXX.XXX:40276 [05/Jul/2019:13:53:33.532] https-in/1: SSL handshake
failure
```

Have someone used this service in the main https config?
Which data (show ...) should I provide to debug this topic?



Hi Aleks,

Could you check with the latest 2.0 snapshot ? An issue about Prometheus was 
fixed (#151 on GitHub). And some others about connections.

prometheus service kills ssl handshake

Hi.

I use HAP 2.0.1 with haproxy service with my image.
After some times (~several hours) the ssl handshake stops working for the https
frontend which offers the prom service.

I have just added this line.

```
http-request use-service prometheus-exporter if { path /mymetrics }
