I'm working on cleanup of a solarwinds orion deployment for a customer and running into an issue where Charts specific to virtualization are showing "No Data Available". Charts like Top Datastore IOPs, and even CPU Consumption by VM, show this. I've confirmed all the basics like the sample being more than the polling interval (not shorter). I've also confirmed that all this information is available in Virtualization Manager itself. If I log in there it will show me specifics about the datastores, and CPU usage by VMs, etc. It's solely the charts in the Web Console.
Please contact SolarWinds support and they will take care about your issue. Thanks
