Did you configure the dashboards in such a way that they will make a circle? For Example:
VM Configuration to Datastore utilization,
Datastore utilization to Host Configuration,
Host Configuration to VM Configuration.
After the configuration you need to go to Dashboards. Select VM Configuration (as in above example the first dashboard)
The dashboards will now switch between each other based on the configured interval (sec).
I did configure it to create a circle. I can get it to work some times if after i configure it i go to one of the dashboards in the circle it will start auto switching. Yet when i go back in to add additional dashboards to the circle, most of the ones that were set before go back to being off, and other times it doesn't save my changes at all. Seems flaky at best.
