Answer

  • Element Software uses readBytes, writeBytes, readOps and writeOps to calculate and display IOPS and Throughput in graphical reports.
  • On a per-volume bases, Element Software tracks cumulative:
    • readOps
    • writeOps
    • readBytes 
    • writeBytes
  • The difference between the two samples and the time delta between sampling is used to calculate and IOPS and Throughput in bytes.
