You will occasionally need vscsiStats to deepen your understanding of an application’s storage profile. This tool is provided with ESX classic but requires configuration and installation for ESXi environments. VMware is planning to add vscsiStats counters to the vSphere Client UI in a future version but until then you will have to perform the following to enable vscsiStats on ESXi.

Seriously. Don’t do it. Don’t do it.
