How the Unified Agent works


How the Unified Agent works

The Unified Agent runs the scripts that discover information about a Storage Foundation host. When the Unified Agent discovers a host, it breaks down the discovery into families, which focuses the discovery on specific functional areas. The discovery of these families occurs at regular intervals.

Table: Discovery of functional areas identifies the families and the frequency in which the Unified Agent discovers them.

After the Unified Agent discovers information about the host, it sends that information to the CommandCentral Management Server. To send the information, the Unified Agent uses xprtld. Xprtld is a light-weight Web server that uses HTTP-based protocols for communication.
