Probe: Hot/Cold Interface Counters (Specific Interfaces)

The hot/cold interface counters (specific interfaces) probe determines hot/cold specific interface counters. It determines if interface counters averaged over "Average Period" are hot (too high) or cold (too low). A given interface (out of the specified list) is considered to be in a hot state if its average counter value is greater than "Max". A given interface (out of the specified list) is considered to be in a cold state if its average counter value is less than "Min". If such undesired state is observed for more-than "Threshold Duration" over the last "Duration" time period, we raise an anomaly. Distinct anomalies are raised for hot and cold states. If more than "Max Hot Interface Percentage" percent of interfaces on a given device are hot, we raise an anomaly. If more than "Max Cold Interface Percentage" percent of interfaces on a given device are cold, we raise an anomaly. Finally, the last "Anomaly History Count" anomaly state-changes are stored for observation.
