Figure 18-2 Monitoring C-Spaces

The following table explains the fields on this screen.

Table 18-2 Monitoring C-Spaces on a C-Hub - Main Screen

Field	Description
C-Space	Shows the names of the c-spaces configured for this c-hub. You can click on a c-space name to view details on the selected c-space. (See Getting Details on a C-Space.)
State	Shows the state of the c-space. The states are Enabled or Disabled and Started or Shut Down. Note that any combination of Enabled/Disabled and Started/Shut Down is possible, as explained in the following description of each state: Enabled. The c-space is accepting new conversations (if started). Disabled. The c-space is not accepting new conversations, but if the c-space is started (running) any existing conversations will be allowed to complete. Started. The c-space is activated and running on the c-hub. If it is also enabled, it is accepting new conversations. If it is disabled, it is not excepting new conversations. Shut Down. The c-space is not running. Any previously existing conversations were terminated.
Enable/Disable	To enable a c-space, select Enable and click Submit. To disable a c-space, select Disable and click Submit. Enable. The c-space will accept new conversations (if started). Disable. The c-space will not accept new conversations. Disabling an active (started) c-space before shutting it down allows for a graceful shutdown. Ideally, once you disable a c-space, you should see existing conversations complete and the c-space eventually become inactive (since no new conversations are allowed). If you wait until there is no conversation activity, you can shut down the c-space without disrupting any conversations.
Start/Shut Down	To shut down an active c-space, select the c-space in the Shut Down list and click Submit. To start a c-space, select the c-space in the Shut Down list and click Submit.
