The Pitfalls of Monitoring Network Traffic

A key consideration for monitoring traffic in lossless networks is that for all practical purposes, treat occurrences of full or high utilization the same as over-utilization. This is because in our experience, most occurrences of full utilization and high utilization have also shown some duration of over-utilization. To understand this in details, refer to Chapter 1, the sections on Defining Full Utilization vs High Utilization vs Over-Utilization and Monitoring Full Utilization vs High Utilization vs Over-Utilization. 在无损网络中监控流量的一个关键考虑因素是，出于所有实际目的，应将出现的充分利用或高利用率等同于过度利用。这是因为，根据我们的经验，大多数满使用率和高使用率情况也会显示一定时间的过度使用。要详细了解这一点，请参阅第 1 章中的 "定义满负荷运行 vs 高负荷运行 vs 过度使用 "和 "监控满负荷运行 vs 高负荷运行 vs 过度使用"。

Next, this section explains pitfalls for monitoring network traffic in production networks using GUI platforms, applications, or scripts. The first point is about calculating the percentage utilization, which is specific to Fibre Channel ports. The second point about the average and peak utilization applies to all types of network ports (Fibre Channel or Ethernet). 接下来，本节将介绍使用图形用户界
