Grafana
2 minute read
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.
