A network device includes one or more ports that are interfaces configured to communicate with other network devices in a network; and circuitry configured to obtain a plurality of data elements, based on operation of the network device, check a predicate with any of the plurality of data elements, and perform any of, responsive to the predicate, i) stream a first set of one or more of the plurality of data elements to a management system, ii) cease a stream of a second set of one or more of the plurality of data elements, and iii) a combination thereof.

Constraint-based event-driven telemetry

Telemetry systems and methods are provided in which data is streamed from to a remote location based on predicate affirmation of pre-established conditions of a system. In one embodiment, a network device comprises a processing device and a memory device configured to store logic instructions. When executed, the logic instructions are configured to cause the processing device to obtain a first set of one or more data elements indicative of one or more conditions of a network in which the network device operates. Also, the logic instructions are configured to cause the processing device to monitor the first set of one or more data elements to determine if a predefined predicate is affirmed and execute a response action when the predefined predicate is affirmed.
