13.2 Starting and Stopping the Sentinel Server

A Sentinel Server is made up of the following components:

Any combination of the above components can be installed in a particular Sentinel Server.

In a distributed installation of Sentinel, it is likely that there will be more than one machine with a Sentinel Server running on it. In this case, all of the Sentinel Servers work together to provide the complete Sentinel functionality.

NOTE:At most one Communication Server and DAS component can be installed across all Sentinel Servers in a distributed Sentinel installation. On the other hand, multiple instances of Correlation Engine and Collector Managers are allowed.

When a Sentinel Server is started or stopped, all components installed in that Sentinel Server are also started or stopped. To start or stop a particular component on a Sentinel Server, use the Servers View under the Admin tab in Sentinel Control Center.

You need to start or stop a Sentinel Server because of the following routine maintenance:
