Sampling Intervals for the collector

What is the interval in seconds that the tool uses to collect data? Is it possible to change the sampling interval to shorter time in order to get more detail from latency and number of IOPS in case there is an All-Flash storage array or local NVMe with submilisecond latency?

  Optical Prime collects data at 2 minute intervals.  It is not adjustable at this time.

  Hi Scott, thanks. Can you tell if you retrieve the performance data from ESXi with the "QueryPerf" method or if the  "I/O operations per second" for the 2 minutes aggregate IOPs for the interval of 2 minutes. We want to make sure we don't miss peaks of burst IO it it is shorter than 2 min.
