最近使用服务器，需要一个监控带宽的东西，很不错，需要服务器可以问我，可以优惠 linux查看服务器带宽具体方法 一、使用speedtest-cli命令查看下载和上传最大流量值 因为命令是python的，所以，需要先下载一个python，用pip下载次命令；
yum -y install python-pip
#等待下载完
pip install speedtest-cli
root@cs:[/root]speedtest-cli Retrieving speedtest.net configuration... Testing from China Unicom (125.119.20.3)... Retrieving speedtest.net server list... Selecting best server based on ping... Hosted by China Telecom TianJin-5G (TianJin) [123.83 km]: 47.213 ms Testing download speed................................................................................ Download: 16.36 Mbit/s Testing upload speed................................................................................................ Upload: 18.58 Mbit/s
二、查看网卡、网络的详情 1.查看服务器网络端口
ifconfig
2.ethtool命令查看宽带大小
ethtool 网卡名称 [root@222 ~]# ethtool eno1 Settings for eno1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: off (auto) Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes Speed: 100Mb/s 带宽为白兆
三、nload命令实时统计网卡带宽使用率 没有nload命令的需要下载；
yum -y install nload
#等待下载完
#直接使用命令查看
nload
#指定网卡进入 nload eno1
Incoming是进入网卡的流量，Outgoing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 四、dstat -n命令实时监测网络的状态
dstat -n
