To the contrary, everything about the DataOn JBOD is exposed through SES and can easily be seen through Powershell using the script outlined on this page. http://www.miru.ch/get-a-brief-storage-spaces-status-overview-via-powershell/
The status of all the components is easy to get, but at this point, the best we can do is run this report. I'm asking if there's a way to have SAM or SRM retrieve this information and alert in real time when an event happens.
