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 high WCPU%

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：
