Nutanix Collector output doesn't has data of 95th Percentile Number of Writes/Reads

I have a question about "95th Percentile Number" for output of Nutanix collector 5.1.

I am running I/O of Read/Write from vdbench on virtul machine of VMware environment (ESXi 7.0U1 and vCSA 8.0.0.10100)  , but the "95th Percentile Number of Writes" and "95th Percentile Number of Reads" values on "vHosts", "vCluster" and "vInfo"are 0.

Could you please advise me on how to solve this problem.
