View Dashboard

Log in to ZStack Cloud, and the page Dashboard is displayed by default. If you already log in, you can also be redirected to the dashboard by choosing Dashboard on the main menu of ZStack Cloud.

The ZStack Cloud dashboard displays information about the Cloud on different widgets, such as resource state statistics, resource utilization trend, resource usage statistics, resource top ranking, recent visit, account or user information, and unread alarm statistics in recent seven days.

Whenever you log in to the dashboard or refresh this page, the dashboard will obtain and display the latest data in real time. By default, widgets in the form of charts and tables automatically refresh every 30 seconds.
By default, the dashboard displays a number of commonly-used widgets, meeting your basic business requirements in O&M and management. If you need to customize the dashboard, click the Customize button at the upper right corner. For details about how to customize the dashboard, see chapter Customize Dashboard.
The dashboard displays widgets in fixed sizes such as large, medium, and small. You can drag and drop widgets to arrange the dashboard layout as per your own preferences.
The dashboard displays resource data of the current zone by default. You can also click the upper left button to switch and show the resource data of all zones.
Charts and tables that show status are following the same colour code, according to which green stands for normal status, red indicates abnormal status, and gray means other status.
The percentage progress bar is displayed in blue (less than 60%), yellow (greater than or equal to 60% and less than 80%), and red (greater than or equal to 80%) to present the usage of current resource in a visualized way.
Some widgets such as Resource State Statistics, Resource Utilization Trend, and Resource Usage Statistics allow you to visit the resource list by clicking the number on the card or the arrow in the upper-right corner. This helps to improve the O&M efficiency.

Customize Dashboard

On the Dashboard page, click Customize, and then the Custom Dashboard page is displayed.

The procedure is detailed as follows.
