Pleroma includes support for exporting metrics via the [prometheus_ex](https://github.com/deadtrickster/prometheus.ex) library.
+Config example:
+
+```
+config :prometheus, Pleroma.Web.Endpoint.MetricsExporter,
+ enabled: true,
+ auth: {:basic, "myusername", "mypassword"},
+ ip_whitelist: ["127.0.0.1"],
+ path: "/api/pleroma/app_metrics",
+ format: :text
+```
+
+* `enabled` (Pleroma extension) enables the endpoint
+* `ip_whitelist` (Pleroma extension) could be used to restrict access only to specified IPs
+* `auth` sets the authentication (`false` for no auth; configurable to HTTP Basic Auth, see [prometheus-plugs](https://github.com/deadtrickster/prometheus-plugs#exporting) documentation)
+* `format` sets the output format (`:text` or `:protobuf`)
+* `path` sets the path to app metrics page
