Nload(CentOS网速流量实时监控软件)的安装和安装过程中的问题解决

I. 安装
wget http://www.roland-riegel.de/nload/nload-0.7.4.tar.gz
tar -xf nload-0.7.4.tar.gz
cd nload-0.7.4
./configure
make && make install

II. 使用

nload -h

Options:
-a period Sets the length in seconds of the time window for average

            calculation.
            平均计算时间长度
            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.
            指定入口流量最大值 单位是kBit/s
            Default is 10240.

-m Show multiple devices at a time; no traffic graphs.

            同时显示多个设备统计信息

-o max_scaling Same as -i but for the graph indicating the outgoing bandwidth

            usage.
            和-i相同，但是是出口流量
            Default is 10240.

-t interval Determines the refresh interval of the display in milliseconds.

            刷新间隔
            Default is 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.
            显示单位
            Default is h.

-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.

            和-u相同，但是为总流量

devices Network devices to use.

            指定网卡
            Default is to use all auto-detected devices.

--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.
运行时使用F2可以查看此页
图形查看

nload -t 200 -i 1024 -o 128 -U M

左右键可以在多个网卡之间切换

网卡流量

**nload eth0
nload -m**
