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 392. 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.

Standard vSwitch Topology and Distributed vSwitch Topology Views

Purpose
A typical VMware environment consists of many interrelated components. Understanding the dependencies between standard virtual switches and other components of your monitored environment and the levels of resources they consume allows you to better understand resource-related issues, potentially affecting the stability of your system. This can help you predict the impact a potential outage may have on your environment, and to prevent such events, by reallocating resources where they are most needed.
The Standard vSwitch Topology View and Distributed vSwitch Topology View visualize the relationships between the objects in your environment through an interactive map. The map illustrates how different components relate to each other, and the levels of the available resources available to them.
Figure 400. Standard vSwitch Topology and Distributed vSwitch Topology Views
The complexity of the information appearing in a dependency map depends on the selected object and the dependencies that object has with other objects within your integrated infrastructure.
In a large multi-component environment, dependency maps are likely complex and may not fit your screen. The NAVIGATOR in the top-right corner allows you to easily set the zoom level by dragging the slider into the appropriate position.
Figure 401. Navigator view
In a dependency map, some objects are represented with container tiles, others with single-object tiles or just icons. Every object in the map includes an indicator of its health.
Figure 402. Object health indicators
Dependencies between the objects in a map are illustrated with single-directional arrows. The color of the arrow reflects the alarm state of the target object: gray for Normal, yellow for Warning, orange for Critical, and red for the Fatal state.
Figure 403. Object dependencies
To find out more about an object appearing in the dependency map, click the object icon. A dwell appears, displaying more details about that object. The type and range of information appearing in the dialog box depends on the selected object’s type. For example, drilling down on a virtual switch shows the switch name, alarm counts top virtual machine consumers, levels of traffic utilization, percentage of packet loss, current traffic types, available bandwidth, the numbers of available and all ports, and the number of active versus standby NICs.
