高输入队列丢弃率(Cisco ifMIB)

System.NetworkManagement.ifMIB_Cisco.NetworkAdapter.HighInputQueueDropRate (UnitMonitor)

监视因该设备上队列已满而丢弃的输入数据包的级别

Knowledge Base article:

摘要

该监视器指示此设备上因队列溢出而丢弃的输入数据包数量。此监视器有两种可能的状态:

配置

可以为此监视器配置以下选项:

选项

定义

默认

间隔

检查设备状态时间间隔(以秒为单位)

240 秒

重试次数

在丢弃时间间隔样本之前,每个监视时间间隔中的尝试次数

3

样本数

监视器更改状态之前的连续样本数

3

超时

样本超时并重新尝试对值进行取样之前等待设备响应的时间量(以毫秒为单位)

3,500 毫秒

阈值

丢弃的数据包数量

1

原因

因输入队列溢出而丢弃的数据包数量超过队列丢弃阈值(默认值为 1)时,此监视器会进入警告状态。输入队列溢出的推导方式为:因队列溢出而丢弃的已指定待接收数据包数量除以队列中的数据包总数。

解决方法

使用运行状况资源管理器,在监视器的“状态更改事件”选项卡上检查状态更改的详细信息。此数据显示计算所得的性能计数器值,该值导致运行状况状态发生更改。有关问题和故障排除过程的详细信息,请查阅设备制造商的文档。
