OpenNMS uses the device's system.sysObjectID to determine what SNMP data should be collected and, independently, what reports to make available--automatically--for the device.
There are cases where the device's sysObjectID includes instance values which may not be available for that specific device, and likewise, the reports would show up empty. Rather than showing an empty report, the reporting servlet checks to see if the corresponding RRD/JRobin file is there and if not, it shows that little error message graphic. To track down specifics, look at the XML report configuration file (/opt/OpenNMS/etc/...) to see which reports are trying to be generated for your device. Methinks there's a logfile to check as well for the corresponding process. At least this was how it used to work... Shane O.
