Use the datastore Performance tab to monitor how Storage I/O Control handles the I/O workloads of the virtual machines accessing a datastore based on their shares.

About this task

Datastore performance charts allow you to monitor the following information:

  • Average latency and aggregated IOPS on the datastore

  • Latency among hosts

  • Queue depth among hosts

  • Read/write IOPS among hosts

  • Read/write latency among virtual machine disks

  • Read/write IOPS among virtual machine disks


  1. Browse to the datastore in the vSphere Web Client navigator.
  2. Under the Monitor tab, click the Performance tab.
  3. From the View drop-down menu, select Performance.
