Recovery

1. This measurement gives an indication if any Gy/Ro Diameter Credit Control Application Request messages were NOT successfully relayed by OC-DRA. OC-DRA can fail to relay Gy/Ro Diameter Credit Control Application Request messages for various reasons as stated above for “Peg Condition”.
2. This measurement is the summation of the following measurements which should be inspected within the same collection interval to further determine the specific cause of failure:
   • TxGyRoAnsGenByOcdraPerCmd
   • TxGyRoAnsGenByDrlPerCmd
   • RxGyRoReqDiscardedCongestionPerCmd

   Note:

   Due to the timing of when measurements are incremented and collected during a collection interval, this measurement may not be the exact sum of the measurements listed above.
