Description: Juniper Networks MIB for monitoring Serving Gateway charging plane data and session accounting on mobile broadband networks.

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 JUNIPER-MOBILITY-SGW-CHARGING-MIB?

JUNIPER-MOBILITY-SGW-CHARGING-MIB (module identity jnxMbgSgwChargingMib) is a Juniper Networks vendor-specific MIB that models the charging (billing/CDR) plane of a Serving Gateway (SGW) in a 3GPP LTE mobile network. It exposes local persistent storage statistics for CDR files awaiting transfer (jnxMbgSgwCgLpsStatsTable: jnxMbgSgwCgFilesOnLcStorage, jnxMbgSgwCgLcStorageAvailSpace), per-Charging-Gateway-Function-group statistics (jnxMbgSgwCgCgfGroupsStatsTable: DRT request/response counters, switchover counts, batch CDR transmission counters), per-CGF server statistics, and a global charging statistics table (jnxMbgSgwCgGlobalStatsTable: jnxMbgSgwCgCdrSendErrors, jnxMbgSgwCgCdrEncodeErrors, jnxMbgSgwCgCdrAllocFailures, jnxMbgSgwCgContFailures, jnxMbgSgwCgCmBearersCreated/Deleted). This makes it useful for monitoring whether charging data records for mobile subscriber sessions are being generated, stored, and successfully forwarded to billing systems — critical for revenue assurance in mobile broadband deployments. It depends on JUNIPER-MOBILE-GATEWAYS (jnxMbgGwIndex/jnxMbgGwName) and JUNIPER-MBG-SMI for its OID placement, and operators evaluating LTE billing pipelines often consult the JUNIPER-MOBILITY-SGW-CHARGING-MIB MIB Browser view to identify these charging counters.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-MOBILITY-SGW-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

  • Juniper Networks Mobility/Serving Gateway (SGW) platforms in 3GPP LTE mobile core deployments

Monitoring Examples

An operator polls jnxMbgSgwCgGlobalStatsEntry for jnxMbgSgwCgCdrSendErrors and jnxMbgSgwCgLpsStatsEntry for jnxMbgSgwCgLcStorageAvailSpace; a rising CDR send-error count combined with shrinking local storage space would indicate the SGW cannot reach its Charging Gateway Function and is at risk of losing billing records once local storage fills.

What Can Be Monitored

  • CDR local storage file count and available space
  • CGF group DRT request/response/timeout counters
  • CGF group switchover and batch CDR transmission counters
  • global CDR send/encode/allocation error counters
  • bearer created/deleted counters

How to Use in IPNetwork Monitor

Example using jnxMbgSgwCgCgfGrpDRTReqTx OID:

Select a Juniper Networks Mobility/Serving Gateway (SGW) platform, 3GPP LTE charging 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 jnxMbgSgwCgCgfGrpDRTReqTx into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the total number of the DRT (Detailed Record Time) request transmitted for the CGF group. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
