Volume view

The Volume view shows the data transfer rates and latency detected for the selected volume. It also identifies the virtual machines that use the highest amounts of the volume resources.The information provided on this tab can help you prevent potential bottlenecks by reallocating disk resources where they are most needed.

Figure 129. Volume view

This view is made up of the following embedded views:

•

Cluster Shared Volume Performance

•

Cluster Shared Volume Total I/O and Latency

Table 78. Cluster Shared Volume Performance

Shows the amount of the volume I/O resources used by the virtual machines associated with the selected volume.

•

I/O Distribution. A pie chart indicating how much each virtual machine associated with the selected volume contributes to the overall use of I/O resources.

•

VM Offenders, Hyper-V Server. The name of the Hyper-V server on which the virtual machine is running.

•

VM Offenders, I/O. The rate at which the virtual machine writes to and reads from the volume.

•

VM Offenders, IOps. The number of disk read and write operations the virtual machine performed from the beginning of the selected time range.

•

VM Offenders, Latency. The latency rate detected for the disk read and write operations the virtual machine performed from the beginning of the selected time range.

•

VM Offenders, Name. The name of the virtual machine.

•

VM Offenders, Hyper-V Server. Shows the Hyper-V server details in the Hyper-V Explorer Summary tab.

Virtual switch monitoring

To review data collected about a specific volume or all volumes, make your selection in the Quick-View.

•

Virtual Switches view

•

Summary - All Virtual Switches view

•

Summary - Virtual Switch view

•

Virtual Switch Topology view

Virtual Switches view

The Virtual Switches tree view lists the available volumes and indicates their severity state.

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

Figure 130. Virtual Switches view

Selecting the All Virtual Switches node displays the overall resource utilization for all virtual switches in your integrated system and identifies the ones that consume the highest amount of network resources in the Summary - All Virtual Switches view on the right. Similarly, selecting a virtual switch node shows switch-specific metrics in the Summary - Virtual Switch view.

Table 80. Description of the View

•

Alarm severity. The state of the most recent alarm raised against the virtual switch.

•

All Volumes. A parent node for the instances of all virtual switches that appear in this view.

•

Volume. The name of the virtual switch.
