GSX Server on a Windows Host
Note: The items in this section describe performance of GSX Server on a Windows
host. For tips on configuring GSX Server on a Linux host, see GSX Server on a Linux
Host on page 193 .
Monitoring Virtual Machine Performance
GSX Server incorporates a set of counters that work with Microsoft’s Performance
console to allow for the collection of performance data from running virtual
machines.
Note: The Performance console is available only on Windows hosts. You cannot
monitor performance for virtual machines on Linux hosts. However, you can monitor
the performance of any guest operating system on the Windows host, including Linux
guests.
The GSX Server performance counters can monitor the following data from a running
virtual machine:
• Reading and writing to virtual disks
• Memory used by the virtual machine
• Virtual network traffic
You can track virtual machine performance only when the VMware Virtual Machine
Console is open or when a virtual machine is running. The performance counters
reflect the state of the virtual machine, not the guest operating system. For example,
the counters can record how often the guest reads from a virtual disk, but they cannot
know how many processes are running inside the guest. An explanation of each
counter appears in the Performance console.
To add counters to track virtual machine performance, use the Windows Performance
console. Complete the following steps.
1. Choose Start > Programs > Administrative Tools > Performance . The
Performance console opens.
