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.

This view is made up of the following embedded views:

For complete information about this view, see Alarms .

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.

Topology views

A typical VMware environment consists of many interrelated components. Understanding the dependencies between specific components in 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 VMware Environment dashboard includes several topology views that 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.

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.

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.

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.

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.

Virtual Switches view

This view is a tree view. It lists the virtual switches that exist in your environment and shows their state.

Selecting the All Virtual Switches node displays overall performance statistics for all virtual switches in your integrated system, and identifies the elements that consume the highest amount of system resources in the Summary - All Virtual Switches view on the right. Similarly, selecting a virtual switch node shows Virtual Machine-specific metrics in the Summary - Standard Virtual Switch view, Summary - Distributed Virtual Switch view, or Summary - Cisco Virtual Switch view on the right. The type of the displayed view reflects the type of the selected virtual switch (standard, distributed, or Cisco).
