14.2 Starting and Stopping a Sentinel Server

A Sentinel server is made up of the following components:

Communication Server
Correlation Engine
DAS
Collector Manager
Reporting Engine
Advisor
Web Server

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:

Upgrades
Patches
Hotfixes
