It can be useful to have some (visual) insight into NignX logs.
This adds [prometheus-nginxlog-exporter](https://github.com/martin-helmich/prometheus-nginxlog-exporter/) to your matrix deployment.
It will provide a prometheus 'metrics' endpoint exposing data from both the `matrix-nginx-proxy` and `matrix-synapse-reverse-proxy-companion` logs and automatically aggregrates the data with prometheus.
Optionally it visualizes the data when [`matrix-grafana`](configuring-playbook-prometheus-grafana.md) is enabled by means of a dedicated dashboard named `NGINX PROXY`

It shows (on the `stats.<your-domain>` subdomain) the dashboards with the graphs that we're interested in. When enabled the `NGINX PROXY` dashboard is automatically added.

Metrics and resulting graphs can contain a lot of information. NginX logs contain information about visitor IP address, URLs, UserAgents and more. This information can reveal usage patterns and could be considered Personally Identifiable Information (PII). Think about this before enabling (anonymous) access. And you should really not forget to change your Grafana password.

Please make sure you change the default Grafana password.
The playbook will automatically integrate the metrics into the Prometheus server provided with this playbook.
## Save metrics on an external Prometheus server
The playbook provides a single endpoint (`https://matrix.DOMAIN/metrics/*`), under which various services may expose their metrics (e.g. `/metrics/node-exporter`, `/metrics/postgres-exporter`, `/metrics/nginxlog`, etc). To enable this `/metrics/*` feature, use `matrix_nginx_proxy_proxy_matrix_metrics_enabled`. To protect access using [Basic Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication), see `matrix_nginx_proxy_proxy_matrix_metrics_basic_auth_enabled`.

You need to enable `matrix_prometheus_enabled` to use Prometheus as data source for nginxlog-exporter.
You need to enable `matrix_prometheus_enabled` as this roles requires Prometheus for data storage.
