适用场景

  • ONTAP 9
  • AFF 和 FAS 系统

问题描述

  • 访问共享/卷时报告间歇性速度缓慢。
  • 一个LIF上的应用程序可能运行正常、但另一个LIF在其他节点、端口或ifgrp上运行速度较慢
  • 网络团队可能会发出NIC端口利用率为100%的警报
  • 在Grafana/AIQUM监控工具中观察到高端口利用率。
    • 在"收获"中、可以在 "收获- cDOT/NetApp详细信息:网络-详细信息 "视图下查看此信息
  • statistics lif show 列表增加了已发送和接收数据的数量
    • statistics show-periodic 间隔为1的命令会按以下示例中的间隔(例如1秒)显示每个LIF的吞吐量
    • iscsi_lif 如果使用iSCSI、则需要此对象、否则、请将 lif 此对象用于CIFS/NFS

示例:
