Top Hosts (Table)

The Top Hosts (Table) views show rate, volume, or utilization for the hosts who exchange the highest volume of data on a particular interface.

The example shows a Top Hosts (Table) view that is configured to show the rate for each listed host. You can configure the view to display rate, utilization, or volume information.

The view contains an interface identification string and a table. The table contains a row for each host with the fully qualified DNS host name (if available) and IP address, as well as the following rate, volume, or utilization information (by default):

• Rate: Maximum rate of outbound data (Maximum From) and inbound data (Maximum To) for each host; average rates of total data (Average Total), outbound data (Average From), and inbound data (Average To) for each host.
• Volume: Amount of outbound data (From), inbound data (To), and all data (Total) for each host.
• Utilization: Maximum percentage of interface capacity that is utilized by the outbound data (Maximum From) and inbound data (Maximum To) for each host; and the average utilization by inbound data (Average From), outbound data (Average To), and total data (Average Total) for each host.

By default, views and reports show the most recent 24 hours of data.

To see a Top Hosts (Table) view in CA Performance Center, add it to a custom dashboard.
