Alert 4010

MCU <mcu> disconnect rate is > 4.

The DMA cluster has lost connection with the specified MCU more than four times in the past 24 hours.

This most likely indicates a network problem, but it could also indicate that the MCU or RealPresence DMA system is under very heavy load.

Alert 4011

MCU <mcu> call failure rate is > 0.4 and < 0.8.

The specified MCU’s number of consecutive failed calls has changed, and the calculated failure rate metric is now between 0.4 (some calls are failing) and 0.8 (most calls are failing).

The RealPresence DMA system keeps track of per-MCU call failure rates not only to alert administrators to call failures, but also to ensure that calls will be routed less often to MCUs with high call failure rates. See MCU Availability and Reliability Tracking on page 148 for more information.

Alert 4012

MCU <mcu> call failure rate is > 0.8.

The specified MCU’s number of consecutive failed calls has changed, and the calculated failure rate metric is now above 0.8.

This indicates that most of the specified MCU’s calls are failing. The RealPresence DMA system keeps track of per-MCU call failure rates not only to alert administrators to call failures, but also to ensure that calls will be routed less often to MCUs with high call failure rates.
