dashboard plugin
|
|
================
|
|
|
|
Dashboard plugin visualizes the statistics of the cluster using a web server
|
|
hosted by ``ceph-mgr``. Like most web applications, dashboard binds to a host
|
|
name and port. Since each ``ceph-mgr`` hosts its own instance of dashboard, we
|
|
need to configure them separately. The hostname and port are stored using the
|
|
configuration key facility. So we can configure them like::
|
|
|
|
ceph config-key put mgr/dashboard/$name/server_addr $IP
|
|
ceph config-key put mgr/dashboard/$name/server_port $PORT
|
|
|
|
where ``$name`` is the ID of the ceph-mgr who is hosting this dashboard web app.
|
|
|
|
These settings can also be configured cluster-wide and not manager specific, eg:
|
|
|
|
ceph config-key put mgr/dashboard/server_addr $IP
|
|
ceph config-key put mgr/dashboard/server_port $PORT
|
|
|
|
If the port is not configured, the web app will bind to port ``7000``.
|
|
|
|
Setting the IP to ``::`` makes the dashboard bind to all available IPv4 and IPv6
|
|
addresses.
|
|
|
|
In addition, make sure that the *dashboard* module is enabled with::
|
|
|
|
ceph mgr module enable dashboard
|
|
|
|
Please note that the dashboard will *only* start on the manager which is active
|
|
at that moment. Query the Ceph cluster status to see which manager is active.
