3.26.13 TxPtrListEmpty
- Measurement ID
 - 10228
 - Measurement Group
 - Diameter Ingress Transaction Exception
 - Measurement Type
 - Simple
 - Measurement Dimension
 - Single
 - Description
 - The number of ingress Diameter Request messages that were discarded because no PTR Buffers were available.
 - Collection Interval
 - 5 min
 - Peg Condition
 - When any DRL thread within the Diameter Process needs to allocate a PTR Buffer from the PTR Buffer Pool and the number of allocated PTRs from a PTR Buffer Pool is less than the maximum configured capacity of PTR Buffers then:
                        
- A PTR Buffer shall be allocated from the PTR Buffer Pool
 - The count for the number of allocated PTRs from a PTR Buffer Pool shall be incremented by one.
 
 - Measurement Scope
 - Server Group
 
Recovery
- If both the peak and average measurements for multiple MPs within a Network Element are consistently near the recommended maximum engineered capacity of an MP when the Ingress Message Rate and/or Diameter Process CPU Utilization measurements are below the recommended maximum engineered capacity of an MP, then a network (IP or Diameter) problem may exist. Looking at these measurements on a time of day basis may provide additional insight into potential network problems.
 - If the peak and average for an individual MP is significantly different than other MPs in the same Network Element then an MP-specific software problem may exist (e.g., a buffer pool leak).
 - It is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729 for assistance if needed.
