Director provides IOPS (I/O operations per second) and disk latency measurements of Server and Desktop OS VDAs. The Machine Utilization panel is extended to display the real-time average IOPS and disk latency for a selected VDA as graphs. Use Historical Machine Utilization to view and export the average IOPS and disk latency measurements for a selected time period. This data helps you troubleshoot disk-related issues on a machine. The Trends -> Resource Utilization tab in Director is extended to display the historical IOPS and disk latency metrics for all VDAs in the selected Delivery Group. The graph displays the average IOPS for the last 24 hours, last month, and last year time periods. The table displays the average and peak IOPS, and the disk latency per machine. This data helps you size and plan disk capacity.

This feature requires Delivery Controller(s) and VDAs version 7.14 or later.
 

Instructions

1. Validate the policy “Enable resource monitoring” is enabled (it is enabled by default).

2. Log into Director and search for the name of the machine in question.
3. In the middle pane, the machine utilization graph will appear tracking the current CPU, Memory and average IOPS. The average IOPS displays the average number of reads and writes to a disk.

4. Select the dropdown for current Disk Latency tracking to see the graph of the delay between a request for data and its return from the disk measured in milliseconds.

5. Select View Historical Utilization to view the historical usage of resources on the selected machine. You can select which charts you’d like to see during a specific time period based off of CPU, Memory, IOPS and Disk Latency.
