1. This measurement is primarily intended to assist in evaluating the need for additional Message Processor (MP) processing capacity at a Network Element and indicates overall MP congestion is occurring.
   • If both the peak and average measurement for multiple MPs within a Network Element are consistently near the recommended maximum engineered capacity of an MP over several collection intervals, then the number of MPs in the Network Element may need to be increased.
   • If the peak and average for an individual MP is significantly different than other MPs in the same Network Element, then an MP-specific hardware, software, or configuration problem may exist or a Diameter peer and/or DNS routing mis-configuration problem may exist.
   • If the problem persists, it is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729.
