HP Insight Control Virtual Machine Management 6.0

Displaying virtual machine host performance information
1. From the HP SIM All Systems tab, select a virtual machine host.
2. Click the VM Performance tab.
The performance information feature can display activity for the most recent 1, 5, 15, 30, or 60 minutes. If
the amount of time requested exceeds the amount available, then all available information is reported.
Virtual machine host performance
The following performance information is provided for VMware ESX Server, Citrix XenServer, and Microsoft
Hyper-V server, except where noted:
NOTE: For accurate performance information, synchronize the CMS clock and the virtual machine host
clock.
• Processor utilization (x CPUs)—The processor utilization on the host, including utilization by the virtual
machines. The number of processor cores or threads on the virtual machine host is reported as x CPUs.
• Virtual machine processor utilization—The processor consumption by all virtual machines on this host.
Processor resources consumed by a virtual machine before powering down the virtual machine are not
included.
• Reserved capacity (All running virtual machines)—The sum of the Reserved System Capacity values for
all Microsoft Hyper-V server virtual machines currently powered up.
• CPU min (All running virtual machines)—The sum of the CPU Min values for all virtual machines currently
powered up divided by the resources available on the host (VMware ESX Server only).
• Memory utilization—The total amount of memory currently in use on the host. The utilization bar indicates
the memory utilization as a percentage of the physical memory configured.
• Virtual machine memory—The total amount of memory currently in use by virtual machines executing
on the host. Memory consumed by a virtual machine before powering down the virtual machine is not
included. The utilization bar indicates the virtual machine memory as a percentage of the physical
memory configured.
• Network throughput—Network traffic transmitted and received on this host. Virtual machine network
throughput is included for VMware ESX Server.
• Network transmit throughput—Network traffic transmitted by this host. Virtual machine network
transmission throughput is included for VMware ESX Server. The utilization bar represents the transmission
percentage of the network throughput.
• Network receive throughput—Network traffic received by this host. Virtual machine network receive
throughput is included for VMware ESX Server. The utilization bar represents the receive percentage
of the network throughput.
• Storage throughput—Storage read and written by this host and all virtual machines on the host. This
utilization bar is always filled.
• Storage read throughput—Storage read by this host and all virtual machines on the host. The utilization
bar represents the read percentage of storage throughput.
• Storage write throughput—Storage written by this host and all virtual machines on the host. The utilization
bar represents the write percentage of storage throughput.
Virtual machine performance
The value averages displayed in this section are relative to the duration of the virtual machine host activity.
Resources consumed by a virtual machine before powering down the virtual machine are not included.
• CPU—The CPU percentage consumed by the virtual machine relative to the total processor capacity of
the virtual machine host.
• vCPU—The CPU percentage consumed by the virtual machine relative to its resource allocation
• Memory—Physical host memory consumed by the virtual machine
