问题描述

StorageGRID设备节点报告所有节点上的high CPU utilization

  • 调查以下问题:
  1. 通过SSH访问有问题的节点并运行 top  以收集资源利用率(lumberjack收集 top -b -n 1 的输出)
  2. 验证 某个进程是否占用了 过多资源:

 PID USER    PR  NI   VIRT   RES   SHR S  %CPU %MEM    TIME+ COMMAND
25086 dds-user  20   0   84.5g  25.2g   9768 S 100.0  40.6  53947:32 dds
15197 cassand+  20   0   80.7g  24.7g  27452 S  37.5  39.7 725:54.86 java
25472 ssm-user  20   0 1709308 192064   7424 S   6.2   0.3   2242:24 ssm
   1 root    20   0   10716   2344   1432 S   0.0   0.0   5:48.81 initSG.sh

  • 在此示例中、DDS服务所 使用的 资源明显高于 StorageGRID环境中的其他资源
