TrafficDirector includes two single-segment, single-domain applications:
Typically, you will use a multisegment, multidomain tool to focus on the portion of your network you want to monitor, then use the single-segment, single-domain applications to zero in on the portion you want to examine more closely.
You can launch the Host Zoom application from the TopN Talkers or All Talkers window. Use Host Zoom to see more information about TopN Talkers or All Talkers with which a selected host is communicating.When you use Host Zoom for TopN Talkers, the default display is graphical and shows only one of seven host traffic criteria at a time. When you use Host Zoom for All Talkers, the default display is tabular and shows all seven host traffic criteria.
To zoom in on an agent displayed in the TopN Talkers window, click the bar graph that represents the agent. The Host Zoom window (Figure 26-1) opens.
Changing to a Tabular Display
To change the Host Zoom display from graphical to tabular, select Applications>Host Zoom (Text). The Host Zoom window displays the same information in a tabular display (Figure 26-2). The window lists the addresses of all the hosts with which the selected host is currently communicating.
The Host Zoom window for TopN Talkers displays Utilization as the default tabular display; however, other display options are available. To change the default display, select an option from the View menu. Table 26-1 lists the available options.
| Option | Display |
| Packets | Number of packets per selected interval. |
| Bytes | Number of bytes per selected interval. |
| Utilization | Utilization for selected interval. |
| Errors | Number of errored packets for selected interval. |
The Host Zoom window for TopN Talkers displays sorts on Address Order by default for the tabular display; however, other sort options are available. To change the default sort option, select an option from the Sort menu. Table 26-2 lists the available options.
| Option | Sorts By |
|---|---|
| Address | Host address. |
| Utilization In | Utilization inbound to the host during the last sample period. |
| Utilization Out | Utilization outbound from the host during the last sample period. |
| Packets In | Cumulative number of packets inbound to the host. |
| Packets Out | Cumulative number of packets outbound from the host. |
| Bytes In | Cumulative number of bytes inbound to the host. |
| Bytes Out | Cumulative number of bytes outbound from the host. |
| Errors In | Cumulative number of errored packets inbound to the host. |
| Errors Out | Cumulative number of errored packets outbound from the host. |
To change the Host Zoom display from a tabular display to a graphical display, select Applications>Host Zoom (Graph). The Host Zoom window displays the same information in a graphical format.
The Host Zoom window for All Talkers sorts on Packets Out by default for the graphical display; however, other sort options are available. To change the default sort option, select an option from the Sort menu. Table 26-3 lists the available options.
| Option | Sorts By |
| Address | Address of different hosts communicating with the selected host on the segment |
| Packets In | Cumulative number of packets inbound to the host |
| Packets Out | Cumulative number of packets outbound from the host |
| Bytes In | Cumulative number of bytes inbound to the host |
| Bytes Out | Cumulative number of bytes outbound from the host |
| Errors In | Cumulative number of errored packets inbound to the host |
| Errors Out | Cumulative number of errored packets outbound from the host |
You can launch the Host History application directly from the All Talkers window. Host History uses a host history graph to display statistics (utilization, packets, bytes, destinations, and errors) about a specific host for a selected agent and domain (Figure 26-3).
The Host History window for All Talkers displays Utilization as the default; however, other display options are available. To change the default display, select an option from the View menu. Table 26-4 lists the available options.
| Option | Display |
|---|---|
| Packets | Number of packets per selected interval. |
| Bytes | Number of bytes per selected interval. |
| Destinations | Broadcasts and multicasts originating from the host only for generic domains. For protocol domains, shows nonunicasts. |
| Utilization | Utilization for selected interval. |
| Errors | Number of errored packets for selected interval. |
The Host History window default display is a line graph. To change the default display, select an option from the Format menu. Table 26-5 lists the available options.
| Option | Display |
| Area | An area graph |
| 2-D Bar | A 2-dimensional bar graph |
| 3-D Bar | A 3-dimensional bar graph |
