在采用 Docker Swarm 的主机系统中, CPU 利用率较高
适用于
- ONTAP 8.2 或更高版本
- Docker Swarm
问题
- 在一个或多个节点上可以看到高 CPU
node -run <node_name> -command top
对节点运行时显示vldb
为 highWCPU%
示例:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
6685 root 101 47 0 290M 109M uwait 1 ??? 410.99% vldb <-----------
1709 root 231 66 0 1092M 449M RUN 7 ??? 141.06% mgwd
1929 root 1 8 - 0K 64K WAIT 3 1141.4 8.79% NwkThd_04
3308 root 1 12 - 0K 64K RUN 0 366.6H 8.69% wafl_exempt00
1927 root 1 8 - 0K 64K WAIT 3 1142.8 8.64% NwkThd_02
3312 root 1 12 - 0K 64K RUN 0 366.6H 8.54% wafl_exempt04
3310 root 1 12 - 0K 64K RUN 1 366.7H 8.50% wafl_exempt02
system node run -node <node_name> rdfile /etc/log/mlog/mgwd.log
包含类似于以下内容的条目,其中aaa.bbb.ccc.ddd
是属于一个或多个 Docker Swarm 服务器的 IP 地址
示例:
