介绍
nload是个很好用的一个工具,功能也很强.只是相对单一,只能查看总的流量,不能像iptraf那样,可针对IP,协议等。可以实时地监控网卡的流量,分Incoming,Outgoing两部分,也就是流入与流出的流量。同时统计当前,平均,最小,最大,总流量的值,使人看了一目了然。

Command line syntax:
nload [options] [devices]
nload --help|-h
Options:
-a period Sets the length in seconds of the time window for average
calculation. //全部数据的刷新时间周期，单位是秒，默认是300.
Default is 300.
-i max_scaling Specifies the 100% mark in kBit/s of the graph indicating the
incoming bandwidth usage. Ignored if max_scaling is 0 or the
switch -m is given.
Default is 10240. //进入网卡的流量图的显示比例最大值设置，默认10240 kBit/s.
-m Show multiple devices at a time; no traffic graphs. //不显示流量图，只显示统计数据。
-o max_scaling Same as -i but for the graph indicating the outgoing bandwidth
usage. //出去网卡的流量图的显示比例最大值设置，默认10240 kBit/s.
Default is 10240.
-t interval Determines the refresh interval of the display in milliseconds.
Default is 500. //显示数据的刷新时间间隔，单位是毫秒，默认500。
-u h|b|k|m|g Sets the type of unit used for the display of traffic numbers.
H|B|K|M|G h: auto, b: Bit/s, k: kBit/s, m: MBit/s etc.
H: auto, B: Byte/s, K: kByte/s, M: MByte/s etc.
Default is h. //设置右边Curr、Avg、Min、Max的数据单位,默认是自动变的.注意大小写单位不同.
-U h|b|k|m|g Same as -u, but for a total amount of data (without "/s").
H|B|K|M|G Default is H. //
devices Network devices to use.
Default is to use all auto-detected devices. //自定义监控的网卡，默认是全部监控的，使用左右键切换。
--help
-h Print this help.
example: nload -t 200 -i 1024 -o 128 -U M
The options above can also be changed at run time by pressing the 'F2' key.常用命令
代码语言：javascript复制# 语法 ： nload 网卡名称 -u 以什么单位显示
nload eth0 -u m- 默认上边Incoming是进入网卡的流量;
- 默认下边Outgoing是网卡出去的流量;
- 默认右边（Curr当前流量）、（Avg平均流量）、（Min最小流量）、（Max最大流量）、（Ttl流量统计）
