In the Sentinel Main interface, click Security Intelligence > Dashboard, then select the dashboard that you want to view.
Click Show dashboard details to see the following information about the dashboard:
The classifiers used to create the dashboard.

Click Show dashboard details in the toolbar.
Click Rename in the toolbar, then rename the dashboard.
Click Save to save the change.
