The following information appears:

Charging Gateway Ready (cGgsnCGFReadyMessages)

Charging Gateway State Change (cGgsnCGFModifyMessages )

Charging Gateway Removal (cGgsnCGFRemoveMessages)

GGSN to GSN/CGF (cGgsnInternalStateMsgs)

CAC Failure (cGgsnSlbCacFailures)

Session Failures (cGgsnSlbSessionFailures )


Charging Gateway Ready (cGgsnCGFReadyMessages)

Charging information is sent from a GGSN to the charging gateway. GTP protocol is used between them. This object consists of the total number of CGF ready messages.

Trigger Condition: The counter is incremented when a CGF ready message is checkpointed to standby.


Charging Gateway State Change (cGgsnCGFModifyMessages )

Significant information related to change in state of  CGF must be checkpointed to GGSN. This object indicates the total number of CGF modify  messages received.

Trigger condition: This counter is triggered when there is a change in CGF state.


Charging Gateway Removal (cGgsnCGFRemoveMessages)

Counts all the messages responsible for CGF removal.

Trigger Condition: This counter is triggered when context is deleted.


GGSN to GSN/CGF (cGgsnInternalStateMsgs)

GGSN sends certain information to other GSNs (SGSN) and CGF.  On failover,  this information must remain consistent. The information includes the following: information element  recovery count sent to the other GSNs for path management, local record sequence number and charging ID, and so on.

Trigger Condition: The counter is incremented for each of these kinds of messages.


CAC Failure (cGgsnSlbCacFailures)

Tracks the  number of CAC Failure notifications sent to SLB.

Trigger Condition: The counter is incremented whenever GGSN sends a CAC failure notification to SLB.


Session Failures (cGgsnSlbSessionFailures )

Tracks the  number of session failure notifications sent to SLB.

Trigger Condition: The counter is incremented whenever GGSN sends a session failure notification to SLB.
