+It is further possible to also run and export metrics from node-exporter and postgres-exporter without installing Prometheus and Grafana. It is possible to use `matrix_prometheus_node_exporter_container_http_host_bind_port` etc., but not always the best choice, for example because your server is on a public network. Use the following variables additionally 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)
+
+```nginx
+matrix_nginx_proxy_proxy_grafana_additional_server_configuration_blocks:
+  - 'location /node-exporter/ {
+  resolver 127.0.0.11 valid=5s;
+  proxy_pass http://matrix-prometheus-node-exporter:9100/;
+  auth_basic "protected";
+  auth_basic_user_file /nginx-data/matrix-synapse-metrics-htpasswd;
+  }'
+  - 'location /postgres-exporter/ {
+  resolver 127.0.0.11 valid=5s;
+  proxy_pass http://matrix-prometheus-postgres-exporter:9187/;
+  auth_basic "protected";
+  auth_basic_user_file /nginx-data/matrix-synapse-metrics-htpasswd;
+  }'
+```
+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.
