Manage Dashboards and Graphs

A dashboard is a set of one or more graphs. A graph is the basic visualization element that can either display a metric over a time interval or only the most recent value. On the Dashboard page, you can create custom dashboards, each combining multiple graphs, which you can use to get insight into how well your application is performing.

You’ll learn the following:

• How to create, update, and remove dashboards.
• How to create, update, and remove graphs.
