+An Ansible code snippet to configure a metrics port is given [here](https://github.com/toralf/tor-relays/?tab=readme-ov-file#metrics).
+
+The Prometheus config for the dashboard _DDoS_ needs to know the _nickname_. In the example below it is set using _address_ (== the hostname):
 
 ```yaml
 - job_name: "Tor-Relay"
   metrics_path: "/metrics-relay"
-  scheme: https
-  tls_config:
-    ca_file: "CA.crt"
-  file_sd_configs:
-    - files:
-        - "foo.yaml"
+  ...
   relabel_configs:
     - source_labels: [__address__]
       target_label: nickname
       regex: "([^:]+).*:(.).*"
       replacement: "my-nick-prefix-${1}"
 ```
 
-and _foo.yaml_ contains the targets:
+where _foo.yaml_ contains the targets:
 
 ```yaml
-- targets: [...
+- targets: ["nick1:1234", "nick2:5678"]
 - targets: [...
 ...
 ```

+My current Prometheus config is [here](./prometheus.yml).
+The self-signed CA is created by the Ansible role mentioned above.
