An issue was found in device-layer monitoring, where a device was submitting interface discard metrics, but was not unresponsive to device status calls that the Enterprise Agent was making to the device. This resulted in a discrepancy in Device Layer views where the interface discard metrics were displayed on the timeline, but not in the Table view. This has been resolved by allowing the interface metrics to be displayed in the table, but noting to users that the interface status is "Unknown".
