Performance monitoring in VMware Workstation

Have you ever been running virtual machines concurrently and felt one of them was causing a problem to your host system? You might just want to do some performance testing or see how much utilization a specific virtual machine is creating.

It is easy to begin monitoring virtual machines with the VMware Workstation  Performance Monitor. Let’s go over the counters that are installed with VMware Workstation. The counters are described in Table A.

Table A

Counter Name Description
Guest Locked Memory Bytes The number of bytes of simulated physical memory that are locked by the guest operating system.
Guest Virtual Physical Memory Bytes The number of bytes of simulated physical memory in the virtual machine.
Network Bytes Received/sec The number of bytes received by the guest operating system over the network.
Network Bytes Sent/sec The number of bytes sent by the guest operating system over the network.
Network Bytes Transferred/sec The number of bytes sent or received by the guest operating system over the network
Network Packets Received/sec The number of network packets received by the guest operating system.
Network Packets Sent/sec The number of network packets sent by the guest operating system.
Network Receive Errors/sec The number of network errors from receiving packets by the guest operating system.
Network Send Errors/sec The number of network errors from sending packets by the guest operating system.
Network Transfer Errors/sec The number of network errors from sending or receiving packets by the guest operating system.
Network Transfers/sec The number of network operations performed by the guest operating system.
Percent Guest Physical Memory Touched The percentage of simulated physical memory recently used by the guest operating system.
Virtual Disk Bytes Read/sec The number of bytes transferred for disk read operations performed by the guest operating system.
Virtual Disk Bytes Transferred/sec The number of bytes transferred to disk operations performed by the guest operating system.
Virtual Disk Bytes Written/sec The number of bytes transferred to disk write operations performed by the guest operating system.
Virtual Disk Reads/sec The number of disk read operations performed by the guest operating system.
Virtual Disk Transfers/sec The number of disk operations performed by the guest operating system.
Virtual Disk Writes/sec The number of disk write operations performed by the guest operating system.

Counters

You can begin to monitor by using the performance management console in Windows. This is a great way to begin monitoring your system for issues or errors.
