Description: Acme Packet SBC system management including CPU, memory, and process health monitoring.

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 APSYSMGMT-MIB?

APSYSMGMT-MIB is Acme Packet's (now part of Oracle Communications) system management MIB for its Session Border Controller (SBC) product line, covering overall system health, resource utilization, and session-level statistics. It exposes a broad mix of performance and capacity data, including CPU and memory utilization, an aggregate system health score, redundancy/HA state, global concurrent session and calls-per-second counts, and capacity metrics for NAT, ARP, and licensing. Its primary use is monitoring both hardware/platform load and software/service status of the SBC: operators track apSysCPUUtil and apSysMemoryUtil for resource exhaustion, apSysHealthScore and apSysState for overall system condition, apSysRedundancy for HA failover readiness, and protocol-specific counters like SIP active local contacts and MGCP gateway endpoints to gauge signaling load. Teams pulling an APSYSMGMT-MIB download typically do so to enable NMS polling of apSysCPUUtil, apSysHealthScore, and the other system-level objects described above, alongside standard SNMPv2 conventions and other Acme Packet MIBs covering SIP/media-specific statistics in the same product family. It is deployed on Acme Packet/Oracle SBC appliances used by carriers and enterprises at the network edge for VoIP/SIP session border control.

IPNetwork Monitor allows you to monitor SNMP objects defined in APSYSMGMT-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

  • Oracle Communications (Acme Packet) 6350 (2016) — high-capacity SBC appliance, still actively sold/documented as of latest SBC OS releases

Monitoring Examples

An operator would poll apSysCPUUtil and apSysMemoryUtil to catch resource exhaustion before it affects call processing, and check apSysHealthScore alongside apSysState for a quick composite view of SBC health. Watching apSysGlobalConSess and apSysGlobalCPS against apSysLicenseCapacity reveals whether the SBC is approaching its licensed session or call-rate limits, while apSysNATCapacity and apSysARPCapacity flag when translation or ARP tables are nearing exhaustion. A drop in apSysRedundancy status combined with a falling apSysHealthScore would indicate an HA failover event or a degrading SBC needing attention.

What Can Be Monitored

  • CPU utilization
  • memory utilization
  • overall system health score
  • HA/redundancy state
  • concurrent session and calls-per-second counts
  • NAT/ARP/license capacity usage

How to Use in IPNetwork Monitor

Example using apSysGlobalConSess OID:

Select an Oracle Communications (Acme Packet) 6350 (2016) 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 apSysGlobalConSess into the Find box to locate it in the OID tree, then select it and click OK. It reports the current total number of concurrent sessions active on the appliance. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if concurrent sessions exceed 80% of the appliance's licensed/rated session capacity, giving you advance warning before you hit a hard session limit. Click Finish to create the monitor; you can adjust any parameter later.

FAQ

How would I catch an Acme Packet SBC approaching resource exhaustion during a call volume spike?
APSYSMGMT-MIB exposes apSysCPUUtil and apSysMemoryUtil for CPU and memory load, along with an aggregate apSysHealthScore and apSysState reflecting overall system condition. Alerting on rising CPU/memory utilization or a dropping health score lets operators intervene before the session border controller starts rejecting new SIP or MGCP sessions.

How can I confirm an Acme Packet SBC's HA pair is ready to fail over if the active unit drops?
The MIB includes apSysRedundancy, which reports the SBC's high-availability/redundancy state. Monitoring this alongside apSysState lets an operator verify the standby unit is synchronized and ready, so a hardware or software failure on the active SBC doesn't interrupt live VoIP sessions.
