2 Dashboard's Web user interface Edit source

2.1 Logging in Edit source

To log in to the Ceph Dashboard, point your browser to its URL including the port number. Run the following command to find the address:

cephuser@adm > ceph mgr services | grep dashboard
"dashboard": "https://host:port/",

The command returns the URL where the Ceph Dashboard is located. If you are having issues with this command, see Section 10.1, “Locating the Ceph Dashboard”.

Log in by using the credentials that you created during cluster deployment (see Section 5.3.2.9, “Configuring the Ceph Dashboard login credentials”).

Tip
Tip: Custom user account

If you do not want to use the default admin account to access the Ceph Dashboard, create a custom user account with administrator privileges. Refer to Chapter 11, Manage users and roles on the command line for more details.

The dashboard user interface is graphically divided into several blocks: the utility menu in the top right-hand side of the screen, the main menu on the left-hand side, and the main content pane.

2.5 Common Web UI features Edit source

In Ceph Dashboard, you often work with lists—for example, lists of pools, OSD nodes, or RBD devices. All lists will automatically refresh themselves by default every five seconds. The following common widgets help you manage or adjust these list:
