Use <code>esxtop</code> on the service console and switch to the disk monitor. Enable views for latency, you will see values like GAVG, KAVG and DAVG. | |||
* '''GAVG''' is the total latency on IO commands averaged over 2 seconds | |||
* '''KAVG''' is the hypervisor IO latency averaged over 2 seconds | |||
* '''DAVG''' is everything outside the ESX server IO latency averaged over the last 2 seconds | |||
Latency occurs when the hypervisor or physical storage cannot keep pace with the demand for IO | |||
