●
Dashboard - The Dashboard consolidates all the visualizations into a single interface. Urika-GX ships with
pre-defined dashboards for resource utilization information. For information about these dashboards, see
on page 79.
●
Panels - The Panel is the basic visualization building block of the GUI. Panels support a wide variety of
formatting options and can be dragged, dropped, resized, and rearranged on the Dashboard.
●
Query Editor - Each Panel provides a Query Editor for the data source, which is InfluxDB on the Urika-GX
system. Information retrieved from the Query Editor is displayed on the Panel.
●
Data Source - Grafana supports many different storage back-ends for retrieving time series data. Each Data
Source has a specific Query Editor that is customized for the features and capabilities that the particular
Data Source exposes. Urika-GX currently supports InfluxDB as its data source.
●
Organization - Grafana supports multiple organizations in order to support a wide variety of deployment
models. Each Organization can have one or more Data Sources. All Dashboards are owned by a particular
Organization.
●
User - A User is a named account in Grafana. A user can belong to one or more Organizations, and can be
assigned different levels of privileges via roles.
●
Row - A Row is a logical divider within a Dashboard, and is used to group Panels together.
Roles
Users and Organizations can be assigned roles to specify permissions/privileges. These roles and their
privileges are listed in the following table:

Each role type can also export performance data via the dashboard. When a new user signs up for the first time,
the default role assigned to the user is that of a Viewer. The admin can then change the new user's role if needed.
All users have a default role of a Viewer when they first log on to Grafana. Administrators can change roles
assigned to users as needed using the Admin menu.
