Really quick and easy vSphere VM disk monitoring tip – use stacked graphs

One handy tip if looking to find the “culprit” VM off a host when assessing which one is causing the IO issues is to use the “stacked graph” functionality that comes in vCenter. It gives a really quick and easy graphical representation of how one VM is performing over another.

To do in vCenter:

  1. Navigate to the ESXi host in question
  2. Select Performance tab on right-hand window and switch to Advanced view
  3. Click Chart options
  4. Choose Real-Time display or the disk resource type
  5. Select the chart type Stacked graph (see below)

stacked graph.

In counters list, select the Read Rate, Write Rate and Usage (Average/Rate) to get an overall view of the activity for your selected controller and click Ok to return to the Performance tab and away you go
