Methods, devices and computer-readable mediums for network device alarm notifications

A network device to generate alarm notifications in a network, the network device comprising:

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network device to
• identify a stateful alarm object instance linked to a primitive event from a network device of a first type, the stateful alarm object instance based on an alarm configuration for an alarm type associated with the network device of a first type,
• determine, based directly on the primitive event, that the primitive event results in a state transition in a state machine for the stateful alarm object instance linked to the primitive event from the network device of a first type,
• decide whether to generate an alarm in response to the state transition, and
• selectively generate the alarm based on the deciding step.

A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by at least one processor at a network device, cause the network device to perform a method for generating alarm notifications in a network, the method comprising:

• identifying a stateful alarm object instance linked to a primitive event from a network device of a first type, the stateful alarm object instance based on an alarm configuration for an alarm type associated with the network device of a first type;
• determining, based directly on the primitive event, that the primitive event results in a state transition in a state machine for the stateful alarm object instance linked to the primitive event from the network device of a first type;
• deciding whether to generate an alarm in response to the state transition;
• and
• selectively generating the alarm based on the deciding step.

A method for generating alarm notifications in a network, the method comprising:

• identifying a stateful alarm object instance linked to other stateful alarm object instances for a network device of a first type in response to a received state transition notification event;
• determining that the received state transition notification event results in a state transition in a state machine for the network device of a first type, the determining based directly on the received state transition notification event;
• deciding whether to generate an alarm in response to the state transition;
• and
• selectively generating the alarm based on the deciding step.

A method for configuring a device to identify alarm conditions at devices in a network, the method comprising:

• obtaining a set of network entity instances from a network data store based on network entity types specified in an alarm configuration for a first network device type;
• instantiating, in a memory, a stateful alarm object instance for each network entity instance in the set of network entity instances;
• listening for primitive events from network devices in the network;
• deciding whether to generate an alarm directly in response to a primitive event from a network device based on a stateful alarm object instance for a corresponding network entity instance in the set of network entity instances;
• and
• selectively generating the alarm based on the deciding step.
