Summary - Distributed Virtual Switch view

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.

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:

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

This view is made up of the following embedded views:

Table 186. Product Information

Description	Shows the name of the selected switch along with some basic configuration information.
Data displayed	• Available Ports. The number of switch ports that are available for use out of the total number of ports.
	• Load Balancing. One or more load balancing policies, indicating how the switch routes network traffic in case of an adapter failure. For example, an uplink may choose a route based on the originating virtual port, IP hash, source MAC hash, physical NIC load, or use a specified fail over order. For more information about these policies, see your VMware documentation.
	• Network I/O Control. Indicates if the selected switch can use network resource pools to prioritize network traffic.
	• Traffic Shaping. Indicates if the traffic shaping policy is enabled or disabled on the selected switch. A traffic shaping policy can restrict the network bandwidth to a port or if a port is configured to temporarily allow transmission of data at higher than normal speeds. For more information about these policies, see your VMware documentation.
	• Type. The type of the switch: VMware Distributed Virtual Switch.
	• Version. The version number of the distributed switch component in your virtual environment.
Where to go next	Drill down on:
	• Product Information. Displays a dwell, providing additional configuration information about the selected distributed virtual switch. To find out more about the network I/O traffic passing through the selected switch, in the dwell, on the right of Network I/O Control, click Enabled. To find out more about the traffic shaping policy, on the right of Traffic Shaping, click Enabled.

Top ESX Hosts

Description	Identifies the ESX hosts with the highest network transmission rate.
Data displayed	• Top ESX chart. For each identified ESX host, the bar chart displays the inbound and outbound transfer rates.
	• Top ESX table, ESX Host. The name of the ESX host identified amongst top network consumers.
	• Top ESX table, Key. The place of the ESX host in the list of top consumers.
	• Top ESX table, Receiving. The average inbound data transfer rate for an ESX host whose network traffic is managed by the selected switch.
	• Top ESX table, Transmitting. The average outbound data transfer rate for an ESX host whose network traffic is managed by the selected switch.
Where to go next	Drill down on:
	• Traffic Type Utilization chart. Displays the Traffic Type Utilization dialog box.
	• Packet Loss, Utilization chart. Displays the Utilization dialog box.

Summary - Cisco Virtual Switch view

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

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 Cisco virtual switches.

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

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

TIP: Cisco virtual switch credentials can also be updated using the Configure Switch button on the Summary - Cisco Virtual Switch view.

Standard vSwitch Topology and Distributed vSwitch Topology views

The Standard vSwitch Topology View and Distributed vSwitch Topology View visualize the relationships between the objects in your environment through an interactive dependency map. The map illustrates how different components relate to each other, and the levels of the available resources available to them.

Topology views are also available for other components on the VMware Environment dashboard. For complete information about topology views, see Topology views .

Summary - All Virtual Switches view

The Summary - All Virtual Switches view displays overall resource utilization information for a group of virtual switches and identifies the elements that consume the highest amount of system resources and may cause potential performance bottlenecks.

Table 187. Top Bandwidth Consumers

Description	Identifies the virtual switches with the highest percentage of network utilization.
Data displayed	• Top Bandwidth Consumers chart. For each identified virtual switch, the chart displays the percentage of network resources available to it that are in use over the selected time period.
	• Top Bandwidth Consumers table, Virtual Switches. The name of the virtual identified amongst top bandwidth consumers.
	• Top Bandwidth Consumers table, Utilization. The percentage of network resources available to it the switch that is currently in use.
Where to go next	Drill down on:
	• Top Bandwidth Consumers chart. Displays the Utilization dialog box.
	• Any switch in the Top Bandwidth Consumers table. Links to the Summary - Standard Virtual Switch view, Summary - Distributed Virtual Switch view, or Summary - Cisco Virtual Switch view, depending on the selected virtual switch type.

Table 189. Top Overall Utilization

Description	Identifies the virtual switches with the highest network transfer rates.
Data displayed	• Top Overall Utilization chart. For each identified virtual switch, the chart displays the network throughput rate over the selected time period.
	• Top Overall Utilization table, Virtual Switches. The name of the virtual switch identified amongst top network consumers.
	• Top Overall Utilization table, Throughput. The current rate of network throughput for the selected switch.
Where to go next	Drill down on:
	• Top Overall Utilization chart. Displays the Utilization dialog box.
	• Any switch in the Top Overall Utilization table. Links to the Summary - Standard Virtual Switch view, Summary - Distributed Virtual Switch view, or Summary - Cisco Virtual Switch view, depending on the selected virtual switch type.
