Reporting › CA Network Flow Analysis Views in CA Performance Center › Interface: Top Hosts › Top Hosts (Table)

Top Hosts (Table)

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

The example shows a Top Hosts (Table) view that is configured to show the rate for each listed host.

The view contains an interface identification string and a table. The table contains a row for each host with the host name or IP address and 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: Number of bytes/megabytes 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.
