3. With a device selected in the MWAM module dialog box, click Statistics.

4. Select GGSN Charging from the Category drop-down box.

The following information is displayed:

> State Transitions (cgprsCgDownTimes)

> Count Access Points (cgprsCgAccPtNum)

> Opened G-CDRs (cgprsCgCdrOpenedNum)

> Closed G-CDRs (cgprsCgCdrClosedNum)

> Current Container (cgprsCgContainerNum)

> Pending G-CDRs (cgprsCgPendingMsgNum)

> Transmitted G-CDRs (cgprsCgSentMsgNum)

> Total CDRs opened (cgprsCgTotalCdrOpened)

> Total containers created (cgprsCgTotalContainerCreated)

### State Transitions (cgprsCgDownTimes)

Number of times the cgprsCgAlarmEchoFailure trap state transitioned since system startup.

### Count Access Points (cgprsCgAccPtNum)

Number of access points for which charging data is collected.

### Opened G-CDRs (cgprsCgCdrOpenedNum)

Number of G-CDRs opened on the GGSN. A G-CDR is opened when a PDP context is activated.

### Closed G-CDRs (cgprsCgCdrClosedNum)

Number of closed G-CDRs on the GGSN that have not been sent to the CG. The G-CDR is closed on encountering trigger conditions. In the event that the G-CDR is closed and the PDP remains active, a new G-CDR is opened for the PDP.

### Current Container (cgprsCgContainerNum)

Number of open or closed charging containers.

### Pending G-CDRs (cgprsCgPendingMsgNum)

Number of pending G-CDR output messages.

### Transmitted G-CDRs (cgprsCgSentMsgNum)

Number of G-CDR output messages transmitted since the charging service was enabled. The transmitted G-CDR is the CDR that was sent to the CG and for which the GGSN got a response from the CG.

### Total CDRs opened (cgprsCgTotalCdrOpened)

Number of CDRs opened on the GGSN, either since system startup or since the last time the charging statistics was cleared.

### Total containers created (cgprsCgTotalContainerCreated)

Number of containers created on the GGSN, either since system startup or since the last time the charging statistics was cleared.
