Filecoin Saturn monitoring for node operators. More powerful and insightful alternative to Saturn Node Dashboard that anyone can run.
Demo
About
Saturn Moonlet provides a node operator with the following: * Real-time and historical metrics about node stats and earnings. * Ability to run arbitrary PromQL queries against node metrics. * Ability to build custom dashboards. * Alerts based on metrics. * Anything else that [Grafana](https://grafana.com) and [Prometheus](https://prometheus.io) can do 😉 It does not require installing any additional software on a Saturn node. You only need [Docker Compose](https://docs.docker.com/compose) to run it locally or on you own server.
How it's made
Saturn Moonlet consists of thee main components. * **Prometheus Exporter** is a Python service that fetches node stats and earnings via the same public HTTP APIs that Saturn Node Dashboard uses. It exposes this info in a simple [text-based](https://prometheus.io/docs/instrumenting/exposition_formats/#text-based-format) format. * **Prometheus** periodically scrapes metrics exposed by Prometheus Exporter and persists these metrics in a local on-disk time series database. Prometheus stores historical data about node stats and earnings. * **Grafana** uses Prometheus as a data source and provides a node operator with powerfull web interface to query and visualize node metrics. It comes with two pre-defined dashboards to overview nodes in the network and see details about a particular node. It also allows to configure alerts.
