Common dashboard operations
The following figure shows the common operations that you can perform on the dashboards.

-
Switch dashboards
The drop-down list shows the name of the current dashboard. You can click the down arrow to switch to another dashboard. To search for dashboards, you can enter a name in the top search bar, or select a tag from the Filter drop-down list.
-
Specify the time range and refresh frequency
After you click the clock icon, you can select a predefined time range from the drop-down panel. For example, you can select Last 5 minutes, Last 12 hours, or Last 30 days. You can also specify the start time and end time to define an absolute time range. In addition, you can set the refresh frequency for the dashboard.
-
Extend the time range
Each time you click the magnifier icon, the time range is extended to twice the original length. The start time and end time are equally extended. For example, if the selected time range is Last 10 minutes and you click the magnifier icon, the start time is extended to 5 minutes earlier and the end time is extended to 5 minutes later.
-
Manually refresh the dashboard
Click the refresh icon to refresh the monitoring data of all panels on the current dashboard.
-
Filter monitoring data
Select an option from the drop-down list to filter the monitoring data displayed on the current dashboard.
