A zone is a defined subset of all devices monitored by the Operations Sentinel server. Only one zone can be open and its node expanded at a time. In Operations mode, under the Operations Sentinel server node, the highest-level nodes represent zones.

By default, a zone named “All” is supplied, and encompasses all systems and other objects that have been configured.

In Figure 1–1, the user is monitoring the Day Shift zone. The small icon in the node beside the name of the zone indicates the most severe unseen alert that is currently raised for a system or other object included in the zone. The icon changes dynamically as alerts are raised, cleared, and marked as seen. This happens for both the open zone and any unopened zones. This is the only monitoring that is done for zones that are unopened.

Zone Administration

When a user with appropriate privileges creates a new zone, a wizard guides him or her through the process. When creating the zone, the user can select from a number of view-creation schemes in the wizard (or none).
