onApp UI diagnostics page shows over utilized nodes over 90% under "nodes with high utilization found" but it's very time consuming to monitor that page every time.
At present there is no way to prevent creation of Vdisks on over ( 90%) utilized NODE'S hence nodes are filling up to 99% and then Node goes into DELAYED PING or INACTIVE state. It will cause all sorts of trouble on storage controllers.
We need a feature to prevent creating new Vdisk on over utilized nodes ( 90%) or at least send an email alert when a node usage goes over 90%.
Hope this small feature will be added in next version :)
