# Prometheus Jellyfin Exporter

This is an exporter that exposes information gathered from Jellyfin for use by the Prometheus monitoring system.

## Installation

Requires Python 3.9 or better.

## Usage

Visit http://localhost:9221/jellyfin?target=1.2.3.4 where 1.2.3.4
is the IP of the Jellyfin server to get metrics from. Specify the `module`
request parameter, to choose which module to use from the config file.

The `target` request parameter defaults to `localhost`. Hence if
`jellyfin_exporter` is deployed directly on the jellyfin host, `target`
can be omitted.

## Authentication

**Using jellyfin.yml config file**

Example `jellyfin.yml` for token authentication:

```yaml
default:
  api_key: "your token"
  verify_ssl: true
```

## Prometheus Configuration

The Jellyfin exporter can be deployed either directly on a Jellyfin server or
onto a separate machine.

Example config for Jellyfin exporter running on Jellyfin server:

```yaml
scrape_configs:
- job_name: 'jellyfin'
 static_configs:
   - targets:
     - 192.168.1.2:9221  # Jellyfin server with Jellyfin exporter.
 metrics_path: /pve
 params:
   module: [default]
```

Example config for Jellyfin exporter running on Prometheus host:

```yaml
scrape_configs:
  - job_name: 'jellyfin'
    static_configs:
      - targets:
        - 192.168.1.2  # Jellyfin server.
    metrics_path: /jellyfin
    params:
      module: [default]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 127.0.0.1:9221  # Jellyfin exporter.
