The Datastore Usage Overview dashboard provides a view of all the virtual machines in your environment in a heat map. The dashboard is suitable for an NOC environment.
The heat map contains a box for each virtual machine in your environment. You can identify the virtual machines that are generating excessive IOPS because the boxes are sized by the number of IOPS they generate.
The colors of the boxes represent the latency experienced by the virtual machines from the underlying storage. An NOC administrator can investigate the cause of this latency and resolve it to avoid potential performance problems.
