Summary - Distributed Virtual Switch view

Purpose

The Summary - Distributed Virtual Switch view illustrates the overall network utilization and the levels of overall network packet loss for a selected distributed virtual switch.

Figure 121. Summary - Distributed Virtual Switch view

How to Get Here
1
On the VMware Environment dashboard, on the Monitoring tab, in the Virtual Environment Overview, select the Virtual Switches tile.
2
In the Quick-View, in the Virtual Switches view, under Distributed Virtual Switches, select a virtual switch.
The Summary - Distributed Virtual Switch view appears on the right.
Configuring NetFlow

NetFlow is a network protocol that enables distributed virtual switches to collect IP traffic information as the data flow enters or exits an interface. These statistics can later be exported and serve as a basis for potential traffic analysis. You can enable this feature on desired distributed virtual switches.

The NetFlow data can be collected from your monitored environment only if your VMware user account includes the following privileges:

•
DVPortgroup.Modify
•
DVSwitch.Modify
•
DVSwitch.PortSetting

For additional information about these privileges, see your VMware documentation.

To enable NetFlow:
1
In the Summary - Distributed Virtual Switch view, click Configure NetFlow.
The Netflow Setting dialog box appears.
Figure 122. Netflow Setting dialog box
2
In the Netflow Setting Dialog box, provide the following information:
•
IP Address and UDP: Type the IP address and port number of the NetFlow collector.
•
VDS IP Address: Type the IP address of the distributed virtual switch.
•
End Time: Select the time when you want the collector to stop obtaining NetFlow data.
•
Active flow export timeout: Type the number of seconds after which an active data flow times out.
•
Idle flow export timeout: Type the number of seconds after which an idle data flow times out.
•
Sampling rate: Type a number indicating how often you want to collect data packets. For example, a value of 2 instructs the collector to obtain data from every second packet.
•
Process Internal Flows: Select this check box if you want to collect data only during network activities between virtual machines on the same host.
