CPU利用率高和性能不平衡警报
适用场景
- ONTAP 9
- AFF - A300
- MGWD
- 主机
问题描述
- 一个节点频繁出现性能不平衡警报
Event: Cluster Load Imbalance Threshold Breached
The performance capacity used counter indicates a load difference of 74% between the nodes on cluster XXX-XXX-XXX and has triggered a WARNING event based on the system threshold of 30%
- 尽管IOPS较低、但CPU利用率始终保持在70%以上
- 前几个CPU域是主机操作系统，主要来自
