Foglight for Hyper-V 5.8.3 - User Guide

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 ones that consume the highest amounts of system resources, potentially causing performance bottlenecks.

This view appears in the Quick-View on the left when you select All Virtual Switches in the Virtual Environment view.

This view is made up of the following embedded views:

Table 81. Alarms

Description	Lists the alarms generated against the monitored virtual switches.
Data displayed	• Alarm Message. An explanation about why the alarm occurred.
	• Severity. Indicates the alarm severity: Warning, Critical, or Fatal.
	• Time. The time at which the alarm was generated.
Where to go next	Drill down on:
	• Alarm Message, Severity, or Time. Displays the Alarm dialog box, showing additional information about the alarm. For more information about alarms in Foglight, see the Foglight User Help. Figure 132. Alarm dialog box

Summary - Virtual Switch view

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

This view appears in the Quick-View on the left when you select a virtual switch in the Virtual Switches view.

This view is made up of the following embedded views:

Table 87. Packets Per Second

Description	Displays the utilization of the selected switch expressed thorough the rate of data packets it receives. This view illustrates the overall switch efficiency.
Data displayed	• Utilization chart, Avg Utilization. The average percentage of the network resources available to the switch that are in use over the selected time period.
	• Utilization chart, Packets per Second. The average rate of the data packets that are sent to the virtual switch over the selected time period.
	• Utilization table, Average Utilization. The average percentage of the network resources available to the switch that are currently in use.
	• Utilization table, Packets per Second. The average rate of the data packets that are sent to the virtual switch.
	• Utilization table, Sum Throughput. The current rate of network throughput for the selected switch.
Where to go next	Drill down on:
	• Utilization chart. Displays the Utilization dialog box. Figure 133. Utilization dialog box

Table 89. Related Items

Description	Shows the numbers and states of the objects in your environment associated with the selected virtual switch.
Data displayed	• Clusters. The number of clusters associated with the selected virtual switch, followed by the related alarm counts.
	• Servers. The number of servers associated with the selected virtual switch, followed by the related alarm counts.
	• Virtual Machines. The number of virtual machines that are associated with the selected virtual switch, followed by the related alarm counts.
	• Virtual Switch. Represents the selected virtual switch. Shows the counts of alarm generated against the switch.
Where to go next	Drill down on:
	• Clusters. Displays the Clusters dwell, showing the names and states of all clusters that are associated with the selected virtual switch. Figure 134. Clusters dwell
	• Servers. Displays the Servers dwell, showing the names and state of the servers associated with the selected virtual switch. Figure 135. Servers dwell
	• Virtual Machines. Displays the Virtual Machines dwell, showing the names and states of all virtual machines that are associated with the selected virtual switch. Figure 136. Virtual Machines dwell
	• Virtual Switch. Displays the Other Items Inventory dwell, showing the state of the selected virtual switch. Figure 137. Other Items Inventory dwell

Virtual Switch Topology view

A typical Hyper-V environment consists of many interrelated components. Understanding the dependencies between virtual switches and other components of your monitored environment 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 Virtual Switch Topology View visualizes 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.

This view appears in the display area when you click View Topology In the Summary - Virtual Switch view.

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.

About frequently asked questions

The Hyper-V Environment dashboard contains the FAQts tab that you can use to ask questions about your monitored systems and review the answers. In the Categories pane, the FAQts view shows several question categories. Clicking a category shows the questions belonging to that category in the Questions pane. From there, clicking a question shows the answer on the right.

This tab also appears in the Hyper-V Explorer. For reference information about this tab, see Hyper-V Explorer FAQts.
