The technical documentation of the grafana microservice, which is a web application that provides visualization and analytics capabilities.

The grafana microservice is a web application that provides visualization and analytics capabilities. Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored.

It has a rich ecosystem of plugins that allow you to extend its functionality beyond the core features.

How it works

Grafana is a web application that can be accessed through a web browser. It let’s you create dashboards that can be used to visualize data from the database.

Thanks to some custom datasource plugins, Grafana can use the various APIs of the United Manufacturing Hub to query the database and display useful information.
