Linux系统如何查看服务器带宽及网络使用情况

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)...

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
