 ### Changing the port and address Prometheus listens on
 
->**Note:**
+NOTE: **Note:**
 The following change was added in [GitLab Omnibus 8.17][1261]. Although possible,
 it's not recommended to change the port Prometheus listens
 on as this might affect or conflict with other services running on the GitLab

 1. Edit `/etc/gitlab/gitlab.rb`.
 1. Disable the bundled Prometheus:
 
-  ```ruby
-  prometheus['enable'] = false
-  ```
+    ```ruby
+    prometheus['enable'] = false
+    ```
 
 1. Set each bundled service's [exporter](#bundled-software-metrics) to listen on a network address, for example:
 
-   ```ruby
-   gitlab_monitor['listen_address'] = '0.0.0.0'
-   gitlab_monitor['listen_port'] = '9168'
-   gitaly['prometheus_listen_addr'] = "0.0.0.0:9236"

-   redis_exporter['listen_address'] = '0.0.0.0:9121'

+     ```
 
 1. Install and set up a dedicated Prometheus instance, if necessary, using the [official installation instructions](https://prometheus.io/docs/prometheus/latest/installation/).
 1. Add the Prometheus server IP address to the [monitoring IP whitelist](../ip_whitelist.html). For example:
 
-  ```ruby
-  gitlab_rails['monitoring_whitelist'] = ['127.0.0.0/8', '192.168.0.1']
-  ```
+    ```ruby
+    gitlab_rails['monitoring_whitelist'] = ['127.0.0.0/8', '192.168.0.1']
