You only needDocker Composeto run it locally or on you own server.
Solution
Saturn Moonlet consists of thee main components.Prometheus Exporteris 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 simpletext-basedformat.Prometheusperiodically 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.Grafanauses 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.
