Virtual machine host performance
After clicking a virtual machine host in the HP Systems Insight Manager (HP SIM) console, click the VM
Performance tab to display the performance information for the host. Activity for the most recent 1, 5, 15,
30, or 60 minutes can be displayed. If the amount of time requested exceeds the amount available, all
available information is reported.
• Virtual machine host performance The following performance information is provided for VMware
ESX Server, VMware GSX Server, VMware Server and Microsoft Virtual Server 2005 hosts, except
where noted.
• 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 of the virtual machines
on this host. Processor resources consumed by a virtual machine before powering off the virtual
machine are not included.
• Reserved capacity (All running virtual machines) The sum of the Reserved System Capacity values
for all virtual machines currently powered on (Microsoft Virtual Server 2005 only).
• CPU min (All running virtual machines) The sum of the CPU Min values for all virtual machines
currently powered on 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 off the virtual
machine is not included. The utilization bar indicates the virtual machine memory as a percentage
of the physical memory configured (Microsoft Virtual Server 2005 and VMware ESX Server).
• Network throughput The network traffic transmitted and received on this host. Virtual machine
network throughput is included for VMware ESX Server.
• Network transmission throughput The 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 The 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 The storage read by this host and all virtual machines on the host. The
utilization bar represents the read percentage of storage throughput.
• Storage read throughput The 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 The storage written by the 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 off the
virtual machine are not included.
