Perform this task to view the following information of a VM: CPU usage, memory usage, I/O throughput statistics, network throughput statistics, disk I/O delay, disk request statistics, CPU frequency, disk usage, number of connections, and partition usage. If a VM is attached to a GPU or vGPU device, you can also view the GPU/vGPU usage, video memory usage, encoding rate, and decoding rate.
ARM hosts do not support the display of the following information: partition usage, GPU/vGPU usage, video memory usage, encoding rate, and decoding rate.
CVM obtains the CPU usage and the memory usage of a VM through CAStools. For correct monitoring of the CPU usage and the memory usage, please install CAStools on a VM.
The system cannot obtain information of a VM and does not display the disk usage or partition usage when the VM is in shutdown or suspended state or CAStools is not installed.
During an online VM migration, the CPU usage, memory usage, I/O throughput, and network throughput of the migrated VM might be incorrect.
When you migrate a VM by using the Host or Host and Storage migration type, the performance monitoring information list might contain two entries about the VM before the migration is finished. After the migration is finished, only one entry about the VM is displayed in the performance monitoring information list.
The disk usage of a VM that uses block device disks might be incorrect on the performance monitoring page.
If you place a CVK host in emergency mode on the CVK platform, you cannot display the network throughput statistics for any VM on that host on the VM performance monitoring page.
On the top navigation bar, click Compute.
From the left navigation pane, select Resource Navigation > All > Resources > Host Pool Name > Host Name > VM Name or Compute > Host Pool Name > Cluster Name > Host Name > VM Name.
Click the Performance Monitor tab.

CPU Usage: CPU usage trend graph. The horizontal axis represents the time, and the vertical axis represents the CPU usage.
Memory Usage: Memory usage trend graph. The horizontal axis represents the time, and the vertical axis represents the memory usage.
I/O Throughput: I/O throughput trend graph for each disk. The horizontal axis represents the time, and the vertical axis represents the I/O throughput in KBps.
Network Throughput: NIC throughput trend graph. The horizontal axis represents the time, and the vertical axis represents the NIC throughput in Mbps.
Disk I/O Delay: Average I/O delay per 30 seconds for each disk. The horizontal axis represents the time, and the vertical axis represents the I/O delay in milliseconds.
IOPS: Average requests of each disk per 30 seconds. The horizontal axis represents the time, and the vertical axis represents the number of requests.
Connections: TCP connection count trend graph for the past 30 minutes. The horizontal axis represents the time, and the vertical axis represents the real-time count of TCP connections in established state. This graph is available only after you install CAStools on VMs.
CPU Frequency: CPU frequency trend graph. The horizontal axis represents the time, and the vertical axis represents the CPU frequency of the host where the VM resides in MHz.
Disk Usage: Disk usage trend graph. The horizontal axis represents the time, and the vertical axis represents the disk usage in percentage. The disk usage is equal to the used space of the disk divided by the total disk space of the VM.
Partitions: Information about each partition. The VM system memory occupies storage space. Therefore, the used system partition size might be different from the used disk size displayed on the page for editing a VM. ARM hosts do not support partition information display.
GPU/vGPU Usage: GPU/vGPU usage trend graph. The horizontal axis represents the time, and the vertical axis represents the GPU/vGPU usage. ARM hosts do not support this field.
GPU/vGPU Video Memory Usage: GPU/vGPU video memory usage trend graph. The horizontal axis represents the time, and the vertical axis represents the GPU/vGPU video memory usage. ARM hosts do not support this field.
GPU/vGPU Encoding Rate: GPU/vGPU encoding rate trend graph. The horizontal axis represents the time, and the vertical axis represents the GPU/vGPU encoding rate. ARM hosts do not support this field.
GPU/vGPU Decoding Rate: GPU/vGPU decoding rate trend graph. The horizontal axis represents the time, and the vertical axis represents the GPU/vGPU decoding rate. ARM hosts do not support this field.
