Synchronization Monitoring and Control
|
|
======================================
|
|
|
|
Configuration changes made at the System Controller are synchronized
|
|
automatically across the |prod-dc|. You can monitor synchronization and enable
|
|
or disable it through the managed attribute of the subcloud.
|
|
|
|
Each subcloud is initially in the unmanaged state. Use the following command to
|
|
change the subcloud to the managed state and synchronize configuration data,
|
|
and to collect alarms from the subcloud.
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ dcmanager subcloud manage <subcloud>
|
|
|
|
The subcloud is synchronized when it is first connected to the |prod-dc| and
|
|
set to managed. A backup audit and synchronization is run at regular intervals
|
|
\(every ten minutes\) for subclouds in the Managed state, synchronizing them to
|
|
the System Controller. You can view the synchronization status for individual
|
|
subclouds on the Cloud Overview page from **Distributed Cloud Admin** \>
|
|
**Cloud Overview**.
|
|
|
|
If a subcloud is not synchronized, it may be in an **Unmanaged** state. The
|
|
subcloud is synchronized immediately when it is changed to the **Managed**
|
|
state.
|
|
|
|
Configuration changes made from the System Controller, and i.e. by specifying
|
|
the ``--os-region-name`` option as ``SystemController`` are synchronized
|
|
immediately. For example, to add an |SNMP| trap destination and immediately
|
|
synchronize this configuration change to all subclouds in the **Managed**
|
|
state, use the following command:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ system --os-region-name SystemController snmp-trapdest-add -i 10.10.10.2 -c my-community
