Datapath monitor alarm

The datapath monitor alarm monitors the load on some of the major hardware components that packets traverse within the Oracle Communications Session Border Controller. These components collectively make up the datapath. The datapath overload alarm is non-health affecting, but when enabled, new SIP calls received by the Oracle Communications Session Border Controller are rejected. Existing calls remain unaffected.

The datapath monitor alarm identifies the physical interface over which the offending traffic was received.

Datapath Watchdog Timer and SNMP Trap Generation

The Oracle Communications Session Border Controller's datapath watchdog timer performs periodic background checks on the continuity of the data path.

Under certain conditions, the internal data path may be interrupted. If packets do not flow long enough for the datapath watchdog timer to expire, a core dump is created and the system can automatically restart or fail over to a standby. This feature is enabled by default and is not configurable.

If SNMP is enabled, the system can also send a trap. Specifically, the system would send the apSysMgmtHardwareErrorTrap with the message Datapath Watchdog: Failures detected on the mainboard.
