the graphs on the DDMI server home page show percentage of on-time scanned devices >80; when this percentage drops lower than 80, the graphs are empty.
there is an article in the HP Knowlege base on this as well;
You should probably check the status following report:
Server > Status > Device status > Active devices; then you can apply a filter on Scanning status and check how many devices were scanned on time and how many are behind for a long period of time.
