RxGyRoInSessionReqNoDestHost

Measurement Group: OC-DRA Diameter Exception

Measurement Type: Simple

Measurement Dimension: Single

Description: The number of in-session Gy/Ro Diameter Credit Control Application Request messages received by OC-DRA without a Destination-Host.

Collection Interval: 5 min

Peg Condition: Each time OC-DRA receives an in-session Gy/Ro Diameter Request message (i.e. CCR-U/T and RAR) that does not contain a Destination-Host.

Measurement Scope: All

Recovery:

  1. This measurement represents an exception condition in which in-session Gy/Ro Diameter Request messages (i.e. CCR-U/T and RAR) are being received without a Destination-Host. Session data is retrieved from the SBR for each in-session Gy/Ro Diameter Request message not containing a Destination-Host. If session data is found, a Destination-Host AVP is populated with the true server name and inserted into the Diameter Request and the Diameter Request is relayed. If session data is not found, the Diameter Request is rejected using "Session Not Found" error condition.
  2. This condition may occur for any of the following reasons that require OC-DRA to be configured to store session state:

    • A client is not capable of learning the OCS server name from the CCA-I
    • The OCS server is not capable of learning the name of a client from the CCR-I

  3. Verify that session state is properly configured if either client or OCS server is not capable in learning each other's hostname.
