Description: Provides management objects for monitoring GPRS charging data record (CDR) generation and transfer to charging gateway functions.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-GPRS-CHARGING-MIB?

CISCO-GPRS-CHARGING-MIB is a Cisco enterprise MIB for managing the charging (billing) function on the GGSN (Gateway GPRS Support Node) in a mobile GPRS/UMTS packet-core network, sitting on the Ga interface toward the Charging Gateway. It exposes configuration objects controlling how Charging Data Records (CDRs) are generated, sequenced, aggregated, and transferred, including enable flags, sequence-number and node-ID options, transfer intervals, queue sizing, and volume thresholds. For monitoring purposes it is primarily a software/service-health MIB: it lets an operator confirm the charging subsystem is enabled, verify CDR queue depth (cgprsCgPktsQSize) isn't backing up, and check that transfer timers and thresholds are set appropriately, which together indicate whether billing data is flowing correctly rather than being lost or delayed. It depends conceptually on the broader 3GPP GPRS/GGSN architecture and Cisco's mobile wireless gateway platform rather than any single IETF standard. It is deployed exclusively on Cisco GGSN nodes within mobile operator packet-core networks, and operators can download the CISCO-GPRS-CHARGING-MIB file to load it into their MIB browser for these GGSN nodes.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-GPRS-CHARGING-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Cisco GGSN (Gateway GPRS Support Node)

Monitoring Examples

An operator would poll cgprsCgEnable to confirm charging is turned on, then check cgprsCgPktsQSize and cgprsCgCdrAggreLimit to see whether the CDR output queue is nearing capacity, which would indicate the charging gateway is not draining records fast enough. Watching cgprsCgTransInterval alongside cgprsCgPathRequest activity helps verify CDR batches are being transferred to the Charging Gateway on schedule. A sustained rise in cgprsCgContainerVolThresh-related counters without corresponding transfers would signal a stalled Ga-interface link between the GGSN and its charging gateway.

What Can Be Monitored

  • charging function enable state
  • CDR sequence numbering
  • CDR node ID inclusion
  • CDR transfer interval
  • CDR output queue size
  • CDR volume threshold
  • non-primary CDR generation

How to Use in IPNetwork Monitor

Example using cgprsCgDownTimes OID:

Select a Cisco GGSN (Gateway GPRS Support Node) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cgprsCgDownTimes into the Find box to locate it in the OID tree, then select it and click OK. The number of occurrences of cgprsCgAlarmEchoFailure traps state transitions since system startup. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
