### Collecting system and Postgres metrics to an external Prometheus server (advanced)
When you normally enable the Prometheus and Grafana via the playbook, it will also show general system (via node-exporter) and Postgres (via postgres-exporter) stats. If you are instead collecting your metrics to an external Prometheus server, you can follow this advanced configuration example to also export these stats.
It would be possible to use `matrix_prometheus_node_exporter_container_http_host_bind_port` etc., but that is not always the best choice, for example because your server is on a public network.
Use the following variables in addition to the ones mentioned above:
Name | Description
-----|----------
`matrix_nginx_proxy_proxy_grafana_enabled`|Set this to `true` to make the stats subdomain (`matrix_server_fqn_grafana`) available via the Nginx proxy
`matrix_ssl_additional_domains_to_obtain_certificates_for`|Add `"{{ matrix_server_fqn_grafana }}"` to this list to have letsencrypt fetch a certificate for the stats subdomain
`matrix_prometheus_node_exporter_enabled`|Set this to `true` to enable the node (general system stats) exporter
`matrix_prometheus_postgres_exporter_enabled`|Set this to `true` to enable the Postgres exporter
`matrix_nginx_proxy_proxy_grafana_additional_server_configuration_blocks`|Add locations to this list depending on which of the above exporters you enabled (see below)
You can customize the `location`s to your liking, just point your Prometheus to there later (e.g. `stats.DOMAIN/node-exporter/metrics`). Nginx is very picky about the `proxy_pass`syntax: take care to follow the example closely and note the trailing slash as well as absent use of variables. postgres-exporter uses the nonstandard port 9187.

It can be worked around by changing the username to `synapse`, for example by using `sed`:
```Shell
$ sed -i "s/synapse_user/synapse/g" homeserver.sql"
$ sed -i "s/synapse_user/synapse/g" homeserver.sql
```
This uses sed to perform an 'in-place' (`-i`) replacement globally (`/g`), searching for `synapse user` and replacing with `synapse` (`s/synapse_user/synapse`). If your database username was different, change `synapse_user` to that username instead.
@ -4,8 +4,8 @@ To install Matrix services using this Ansible playbook, you need:
- (Recommended) An **x86** server ([What kind of server specs do I need?](faq.md#what-kind-of-server-specs-do-i-need)) running one of these operating systems:
- **CentOS** (7 only for now; [8 is not yet supported](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/300))
- **Debian** (9/Stretch or newer)
- **Ubuntu** (16.04 or newer, although [20.04 may be problematic](ansible.md#supported-ansible-versions))
- **Debian** (10/Buster or newer)
- **Ubuntu** (18.04 or newer, although [20.04 may be problematic](ansible.md#supported-ansible-versions))
- **Archlinux**
Generally, newer is better. We only strive to support released stable versions of distributions, not betas or pre-releases. This playbook can take over your whole server or co-exist with other services that you have there.
