Color Indicator Interpretation in Top Talkers Views

In several dashboards within FNM Manager, such as the Traffic Top Talkers Incoming panel, visual indicators are used to help identify potential anomalies in network traffic. These views highlight the hosts with the highest traffic, either in bandwidth (Mbps) or packets per second (PPS), allowing for quick situational awareness.

To assist with interpretation, each host entry may include a colored status indicator that reflects its current behavior compared to historical data.

Meaning of the Color Indicators

The colored indicators are designed to convey the relative status of a host based on recent traffic trends:

Red: Current value exceeds the historical maximum value.
Yellow: Current value exceeds 150% of the average value.
Gray: Current value is within normal operational thresholds.

These indicators are available for both Mbps and PPS metrics and help distinguish between bandwidth-heavy usage and high-packet-rate behavior.

Purpose and Benefits

The purpose of these indicators is to improve the readability and usability of the data presented in traffic reports. They provide:

Immediate visual feedback on the current state of each host.
A simplified way to identify which hosts are behaving abnormally.
Enhanced decision-making for network engineers and NOC operators without needing to manually compare numeric values.

By using these visual thresholds, FNM Manager enables faster detection of irregular patterns that may suggest congestion, attacks, or misconfigurations.
