Performance

Click on Performance tab to view the resource utilization data. Detailed date, time and information of the chart will be shown upon mouseover.

On the Overview tab, charts for CPU, GPU, System Memory, GPU Memory, Network, Disk, Volume, and iSCSI are displayed.

CPU

You can see the overall CPU usage of User, System and I/O Wait. CPU load could be high when Resource Monitor is first launched, because the system needs to collect its resource data and load the UI page at the same time.

Term Explanation

GPU

The overall GPU utilization will be shown. You can switch between GPU and GPU Memory in the drop-down menu.

Note:

System Memory

The overall memory usage of physical memory and swap space will be shown. Memory usage remains high because the system stores frequently accessed data in cache, so the data can be quickly obtained without accessing the hard disk. Cache memory will be released when overall memory is insufficient.

High swap space usage indicates insufficient system memory, and will also affect the system performance. You can view the rate of swap in and swap out by choosing Swap from the drop-down menu on the top.

Network

The network flow chart displays sent and received data in KB's per second. If PPPoE is connected, its transfer rate will also show up on the chart.

Disk

You can choose to view the overall disk utilization, transfer rate or IOPS by clicking the drop-down menu at the top of the chart. You can click View All at the bottom to select more disks by ticking the checkboxes to add their data to the chart.

Volume

This page displays the overall transfer status of volumes. Click the drop-down menu above the chart to view transfer utilization, transfer rate, or IOPS. Click the View All button to select individual volumes and add them to the chart.

iSCSI

This page displays the overall status of currently running iSCSI LUNs. Click the drop-down menu above the chart to select a LUN and view its status. Three charts are displayed by default, which are Throughput, IOPS and Latency. For more detailed information, click the Choose Charts button to select other charts that you want to view.
