Measurement Group: Diameter Ingress Transaction Exception

Measurement Type: Simple

Measurement Dimension: Single

Description: The number of ingress Diameter Request messages received that are discarded by MP without Error Answer due to MP Overload Control or Maximum IMR Limitation.

Collection Interval: 5 min

Peg Condition: Pegged when Diameter Request message is discarded.

Measurement Scope: Server Group

Recovery:

  1. The MP is approaching or exceeding its maximum configured MPS limitation. If this value is not set to the MP's engineered traffic handling capacity, then the maximum MPS capacity allowed may need to be changed. Contact My Oracle Support (MOS) for assistance.
  2. If one or more MPs in a server site have failed, the traffic will be distributed between the remaining MPs in the server site. MP server status can be monitored from the Status & Manage > Server page.
  3. The mis-configuration of Diameter peers may result in too much traffic being distributed to the MP. The ingress traffic rate of each MP can be monitored from the Status & Manage > KPIs page. Each MP in the server site should be receiving approximately the same ingress transaction per second.
  4. There may be an insufficient number of MPs configured to handle the network traffic load. The ingress traffic rate of each MP can be monitored from the Status & Manage > KPIs page. If all MPs are in a congestion state then the offered load to the server site is exceeding its capacity.
  5. The Diameter process may be experiencing problems. The alarm log should be examined using the Alarms & Events page.
  6. If the problem persists, contact My Oracle Support (MOS).
