Description: Acme Packet SBC DNS application-layer gateway configuration and resolution statistics.

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 APDNSALG-MIB?

APDNSALG-MIB is an Acme Packet (now Oracle) vendor MIB covering the DNS Application Layer Gateway feature on their Session Border Controllers. It exposes configuration data (DNS server table, realm, domain suffix, server IP address) and per-realm statistics for DNS ALG resolution activity. Its monitoring value is mainly software/service status: whether each configured DNS ALG server is reachable and correctly associated with its realm, which affects SIP call routing reliability. As a module in Acme Packet's enterprise tree it depends on the broader Acme Packet SBC MIB structure rather than external standards MIBs. It is deployed on SBCs at the edge of service-provider or enterprise VoIP/SIP networks. Engineers can download the APDNSALG-MIB file directly to load it into their MIB browser.

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

Acme Packet (Oracle) Session Border Controller

Monitoring Examples

apDNSALGServerStatusTable/apDNSALGServerStatusEntry with apDNSALGServerIpAddress, apDNSALGServerRealm, and apDNSALGDomainSuffix let an admin confirm each configured DNS server per realm is reachable; an apDNSALGServerStatus entry flipping to down flags a lookup failure risk for SIP call routing. apDNSALGStatsTable/apDnsALGStatsEntry keyed by apDnsAlgClientRealmIndex provides per-realm request/response counters useful for spotting a spike in failed DNS ALG lookups tied to a specific customer realm.

What Can Be Monitored

DNS ALG server status
configured DNS server IP addresses
domain suffix per realm
per-realm DNS ALG statistics

How to Use in IPNetwork Monitor

Example using apDnsAlgTotalQueries OID:

Select an Acme Packet (Oracle) Session Border Controller 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 apDnsAlgTotalQueries 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 queries sent in life time received on DNS-ALG config realm. 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.
