Claim 7:
8. A method comprising:
determining, by one or more processors and at a first time, first telemetry data associated with a first subset of a group of network node devices, wherein the group of cable modem devices is associated with a cable network including one or more devices located downstream from a first network node device;
determining, at a second time, second telemetry data associated with a second subset of the group of cable modem devices, wherein the second subset of the group of cable modem devices is different than the first subset of the group of cable modem devices;
determining, first streaming trap data indicative of an impairment of a first cable modem device of the second subset of the group of cable modem devices, wherein the first telemetry data and the first streaming trap data, and the second telemetry data are received from a cable modem termination system that communicates with the group of cable modem devices via the first network node device, wherein the first streaming trap data includes a micro-reflection;
determining, based on the second telemetry data indicating the impairment of the first cable modem device, a full poll of the one or more devices included within the cable network downstream from the first network node device, the full poll comprising:
identifying a first network tap upstream from a first cable modem device of the group of cable modem devices;
determining third telemetry data associated with the first network tap;
identifying all remaining network taps in the cable network; and
determining, subsequent to identifying the remaining network taps, fourth telemetry data associated with the remaining network taps and any cable modem devices located downstream from the remaining network taps;

generating first performance data associated with the first network node device;
determining, based on a comparison between the first performance data and an event criterion, an occurrence of an intermittent event associated with the first network node device; and
determining, based on a machine learning model and the occurrence of only the intermittent event and without identifying a prior sustained event, a probability value indicative of a probability of a future occurrence of a sustained event;
determining that the probability value satisfies both a first threshold and a second threshold that is different than the first threshold; and
determining, based on the probability value satisfying the first threshold and second threshold, that a future sustained event will occur.
