Top Hosts - Pie

The Top Hosts (Pie) views show the hosts that account for the highest volumes of network traffic on the selected interface. The example graphic shows the view in the CA Performance Center Console.

The table includes the following information by default:

Identifier

Identifies the interface that is used for the report. The identifier string consists of the router name, interface name, and interface description (under the view title).

(NPC) The identifier line also includes the interface speed.

Host Name

Identifies the host server by its fully qualified DNS name (if available) and IP address.

Total

Records the total amount of data for the host on the interface, expressed in a scale that is appropriate for the highest-volume host.

Percent

(CA PC) Records how much the host consumes out of the total traffic that is displayed.

Performance Center views show the data from the time range that is defined for the page.
