Monitoring Guest Operating System
Performance 2
This section describes how to install and view VMware-specific performance data for virtual machines that
run Microsoft Windows operating systems. VMware provides performance counters that enable you to view
data on many aspects of guest operating system performance for the Microsoft Windows Perfmon utility.
Some virtualization processes dynamically allocate available resources depending on the status, or
utilization rates, of virtual machines in the environment. This can make obtaining accurate information
about the resource utilization (CPU utilization, in particular) of individual virtual machines, or applications
running within virtual machines, difficult. VMware now provides virtual machine-specific performance
counter libraries for the Windows Perfmon utility that enable application administrators to access accurate
virtual machine resource utilization statistics from within the Windows Perfmon utility.
You can take advantage of virtualized CPU performance counters to use performance tuning tools inside the
guest operating system. See the vSphere Virtual Machine Administration documentation.

Analysis
VMware-specific performance objects are loaded into Microsoft Windows Perfmon and enabled when
VMware Tools is installed.
To display a performance chart for any performance object, you must add counters. See “View Performance
Statistics for Windows Guest Operating Systems,” on page 101

You can display VMware specific statistics in the Microsoft Windows Perfmon utility.
Prerequisites
Verify that a virtual machine with a Microsoft Windows operating system and VMware Tools is installed.
Procedure
1 Open a console to the virtual machine and log in.
2 Select Start > Run.
3 Enter Perfmon and press Enter.
4 In the Performance dialog box, click Add .
