Grafana
Grafana is an open-source analytics and monitoring platform that integrates with various data sources, allowing users to visualize and analyze metrics and logs. It provides a flexible and powerful interface for creating, exploring, and sharing dashboards, which are collections of panels that display visualizations of data.
Grafana should not be installed on either a validator node or a monitoring machine. It is recommended to deploy Grafana on a separate dedicated machine or consider using a cloud-based solution.
