1、Mtr介绍: 一个不错的网络连通性判断工具
2、安装: yum install mtr -y 或者 dnf install mtr -y
3、基本使用: mtr 96.45.189.193

使用界面
4、名词解释
Host:主机ip地址
Lost:每个对应IP的丢包率
Snt: 设置发送的ping次数, 默认值是10 可以通过参数 -c 来指定
Last: 最近一次的返回延时
Avg:是平均值 发送ping包的平均延时
Best: 最短的延时
Wrst: 最长的延时
StDev: 标准偏差
5、常规用法

mtr -n 96.45.189.193 不显示host名称
① mtr -c 5 96.45.189.193 设置发送5次之后自动停止
② mtr -s 256 96.45.189.193 设置每次发送的数据包大小为 256
