1.查看服务器网络端口
ifconfig
查看带宽大小:sudo ethtool xxx
sudo ethtool eth0
[root@centos7-spider ~]# ethtool eth0

nload
Device eth0 [10.16.169.14] (1/2):
====================================================================
Incoming:
Curr: 27.99 kBit/s
Avg: 33.14 kBit/s
Min: 19.02 kBit/s
Max: 116.44 kBit/s
Ttl: 74.46 GByte
Outgoing:
Curr: 20.26 kBit/s
Avg: 83.46 kBit/s
Min: 17.72 kBit/s
Max: 3.19 MBit/s
Ttl: 145.30 GByte
Incoming也就是进入网卡的流量,Outgoing,也就是从这块网卡出去的流量,每一部分都有下面几个。
Curr:当前流量
Avg:平均流量
Min:最小流量
Max:最大流量
Ttl:总流量
nload默认的是eth0网卡,如果你想监测eth1网卡的流量,可以使用下面的命令。
nload eth1
同时查看多个网卡的流量情况
nload -m
//结果如下:
