Monitoring Virtual Machines

Virtual machines share many of the characteristics of physical systems (like storage and network interaction), but they do not have direct access to the hardware that is used to process. Each virtual machine runs on a guest operating system (for example, Microsoft® Windows® XP), and is allocated access to a specific set of the server’s resources. This includes the number of processors and the amount of memory it can leverage.

You can monitor the usage of virtual machine resources when you select one or all virtual machines in the Quick View. The information appearing in this view can help you discover potential resource-level issues such as spikes in CPU, memory and disk usage, and to reallocate resources, when required.

To explore virtual machines:

On the navigation panel, under Dashboards, click vCloud Director > vCloud Environment.

On the vCloud Environment dashboard, on the Monitoring tab, click the Virtual Machines tile.

The Quick View refreshes, showing the performance summary of all selected virtual machines in the Summary - All Virtual Machines view.

Figure 29. Summary - All Virtual Machines view

This view displays the overall resource utilization information for all virtual machines in the monitored vCloud, and identifies the elements that consume the highest amount of system resources. For more information, see Exploring the Collective Use of All Virtual Machine Resources.

In the left pane, select a virtual machine.

The Quick View refreshes, showing a virtual machine summary view on the right.

Figure 30. Virtual Machine Summary view

This view displays the levels of system resource consumption for a selected organization, organization vDC, or provider vDC. For more information, see Exploring the Use of Individual Organization, Organization vDC, or Provider vDC Resources.

Exploring the Collective Use of All Virtual Machine Resources

The Summary - All Virtual Machines view displays the levels of resource utilization for all virtual machines, broken down into four simple views. This view identifies the virtual machines that consume the highest amount of system resources. It can help you learn about the resource levels used by all virtual machines, and to identify and prevent potential bottlenecks by reallocating resources where they are most needed.

This summary view appears on the right of the Quick View when you select the Virtual Machines tile.

Figure 31. Summary - All Virtual Machines view

The information appearing on this view is organized into four views: Top CPU, Memory, Network, and Datastore Consumers views.

For information about the All Alarms view also appearing in this summary, see Managing Alarms .

Top CPU, Memory, Network, and Datastore Consumers views

Use these views to identify the virtual machines with the highest consumption of CPU, memory, network, and disk resources.

Foglight™ for vCloud Director populates these views using the metrics collected by Foglight for VMware. For more information about the metrics appearing in these views, see the Managing Virtualized Environments User and Reference Guide.

Table 11. Top CPU, Memory, Network, and Datastore Consumers views
Data	Description
Virtual Machine	The name of the virtual machine.
Top CPU Consumers
Used Hz	The amount of CPU processing speed the virtual machine spends on executing system code and user programs, during the selected time range.
Top Memory Consumers
Consumed	The amount of memory the virtual machine consumes during the selected time range.
Top Network Consumers
Rate	The rate at which the virtual machine transfers data to or from the network during the selected time range.
Top Disk Consumers
Rate	The rate at which the virtual machines reads or writes data to the disk during the selected time range.

Exploring the Use of Individual Virtual Machine Resources

The Virtual Machine Summary view displays the amounts of system resource consumption for a selected virtual machine. This view can help you to identify and prevent potential bottlenecks by reallocating resources where they are most needed. It appears on the right in the Quick View when you select a virtual machine in the Virtual Machines pane.
