This repository hosts a Prometheus metrics exporter for
[Paperless-ngx][paperless], a document management system transforming physical
documents into a searchable online archive. The exporter relies on [Paperless'
REST API][paperless-api].
An implementation using the API was chosen to provide the same perspective as
web browsers.
## Usage
`prometheus-paperless-exporter` listens on TCP port 8081 by default. To listen on
another address use the `-web.listen-address` flag (e.g.
`-web.listen-address=127.0.0.1:3000`).
TLS and HTTP basic authentication is supported through the [Prometheus exporter
toolkit][toolkit]. A configuration file can be passed to the `-web.config` flag
([documentation][toolkitconfig]).
See the `--help` output for more flags.
## Installation
