What network utilization threshold is set for alerting purposes?

The threshold for network utilization alerting is set to higher than 90% in 3 of 5 one-minute intervals. This level is chosen because it reflects a critical point where network performance may start to degrade significantly, impacting the user experience and application performance. When utilization reaches this level consistently over multiple intervals, it indicates that the network may be under strain, potentially leading to increased latency, packet loss, or service disruptions.

Setting the threshold at 90% ensures that alerts are generated before reaching maximum capacity, allowing for proactive management and troubleshooting to maintain optimal network performance. Additionally, this threshold strikes a balance between being sensitive enough to catch genuine issues while minimizing unnecessary alerts for minor fluctuations in usage. This is why this specific threshold is appropriate for alerting purposes in network management.
