The following information is known about the vSAN Cluster:
* vSAN 7.x Cluster
* vSAN node count: 8

NEW QUESTION 33
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?
- A. vSAN performance verbose mode is not enabled.
- B. vSAN proactive tests haven't been run yet.
- C. vSAN performance service is turned off.
- D. vSAN network diagnostic mode is not enabled.
Answer: C
Explanation:
Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.
