rebelcore/jellyfin_exporterrebelcore/jellyfin_grafana
A ready-made Grafana dashboard for the metrics the Jellyfin exporter produces. Import the JSON, point it at your Prometheus datasource and you have streaming, library and user panels out of the box.
rebelcore/minecraft_exporter
Prometheus exporter for Minecraft servers. Tracks player counts, positions in the world, and server health so you can build alerts and Grafana panels around a live world.
docker run -d -p 9150:9150 \
-v /path/to/world:/world:ro \
rebelcore/minecraft_exporterrebelcore/jenkins-plugin-pagerduty-v2
Trigger, acknowledge and resolve PagerDuty incidents straight from a Jenkins pipeline, so a failing build pages the on-call engineer without a separate alerting hop.
