Description

Histogram of Gx-Prime session refresh durations.

Collection Interval

5 min

Peg Condition

When a Gx-Prime session record is refreshed, the appropriate histogram instance shall be incremented by 1. Gx-Prime sessions are refreshed during RAA processing.

Note:

Binding-dependent session records are stored only if topology hiding applies to the AF that created the session.

Measurement Scope

Network, Place Association, Resource Domain

Recovery

1. This measurement shows a histogram of Gx-Prime session refresh durations, providing information to assist in setting the Stale Session Timeout for APNs that use this interface. If the Stale Session Timeout for an APN using the Gx-Prime interface is set too short, the session audit will remove the session prematurely, possibly causing signaling failures for subsequent in-session request processing needing topology hiding translations.

   Note:

   This measurement applies only sessions for which session state is being maintained. Policy DRA does not maintain Gx-Prime session state unless Topology Hiding applies to the session.

   Histogram measurements consist of 101 array entries:

   • 0 – Overflow. Incremented if duration is greater than 9,830 minutes.
   • 1-5 – 1 minute buckets. Incremented for durations between 0 and 5 minutes.
   • 6-10 – 5 minute buckets. Incremented for durations between 0 and 30 minutes.
   • 11-15 – 10 minute buckets. Incremented for durations between 30 and 80 minutes.
   • 16-20 – 30 minute buckets. Incremented for durations between 80 and 230 minutes.
   • 21-100 – 120 minute buckets. Incremented for durations between 230 and 9,830 minutes.
