Predictive network maintenance

One or more non-transitory computer-readable medium storing computer program code comprising sets of instructions to:

• obtain historic records of hardware metrics for a plurality of network interfaces in a network;
• determine an average of the hardware metrics over a specified time span for a plurality of time spans;
• determine feedback metrics for the plurality of network interfaces for each of the plurality of time spans;
• generate a histogram plotting a frequency of the feedback metric for specified ranges of the hardware metric, wherein data points used to generate the histogram being a pair including a hardware metric value and a feedback metric value;
• determine a threshold value for the hardware metric by iteratively determining whether a hardware metric bin of the histogram meets a specified non-zero value for the feedback metric starting from a highest hardware metric bin of the histogram, the threshold value being determined to be an upper value of a particular hardware metric bin having the feedback metric that meets the specified non-zero value;
• obtain new records of hardware metrics for the plurality of network interfaces;
• and
• determine that one or more network interfaces of the plurality of network interfaces need maintenance based on an average of the hardware metrics in the new records for the one or more network interfaces over the specified time span meeting or exceeding the determined threshold value for the hardware metric.
