Docker监控-stats

查看容器统计信息，查看容器的CPU利用率、内存的使用量以及可用内存总量。

[root@bogon ~]# docker stats 44ab452b4
CONTAINER CPU % MEM USAGE/LIMIT MEM % NET I/O
44ab452b4 0.00% 4.448 MB/1.027 GB 0.43% 2.406 kB/648 B
CONTAINER CPU % MEM USAGE/LIMIT MEM % NET I/O
44ab452b4 0.00% 4.448 MB/1.027 GB 0.43% 2.406 kB/648 B
^C[root@bogon ~]#

一直会运行 ，可以用 ctrl+c终止。

还可以查看，容器通过网络发送和接收的数据总量。

一方面我们发送icmp包ping百度

root@44ab452b47fe:/# ping www.baidu.com

另一方面我们在终端上输入命令 可以看待最后一列一直在增大
