Prometheus Metrics

Pleroma includes support for exporting metrics via the 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 documentation)
format sets the output format (:text or :protobuf)
path sets the path to app metrics page

`/api/pleroma/app_metrics`

Exports Prometheus application metrics

Method: GET
Authentication: not required by default (see configuration options above)
Params: none
