最好用的轻量级Linux网络流量实时监控工具nload

    个人觉得nload是个很好用的轻量级Linux网络流量实时监控工具,功能也很强.安装软件后,输入命令nload后,nload软件会很直观的显示流量的即时状态,上半部分ncoming是进入网卡流量,下半部分Outgoing是从这块网卡出去的流量,每部分都有当前流量(Curr)、平均流量(Avg)、最小流量(Min)、最大流量(Max)、总流量(Ttl)。nload的工作界面如下所示:

    官网及下载:http://www.roland-riegel.de/nload/index.html
    http://www.roland-riegel.de/nload/nload-0.7.4.tar.gz

    源码包方式安装:
    wget http://www.roland-riegel.de/nload/nload-0.7.4.tar.gz
    tar -zxvf nload-0.7.4.tar.gz
    cd nload-0.7.4
    ./configure;make;make install

    yum方式安装:
    yum install -y nload

    使用:
    直接输入nload回车即可,也可以指定网卡,如nload eth1,还可以指定是以K、M和G来显示流量,如nload -u M显示的流量是以MB为单位的,nload -u G显示的流量是以GB为单位的。

    查看还有哪些参数或选项:
    [root@wdlinux ~]# nload -h

    nload version 0.7.4

    Command line syntax:

    nload –help|-h

    Options:
    -a period Sets the length in seconds of the time window for average
    calculation.
    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.
    -m Show multiple devices at a time; no traffic graphs.
    -o max_scaling Same as -i but for the graph indicating the outgoing bandwidth
    usage.
    Default is 10240.
    -t interval Determines the refresh interval of the display in milliseconds.
    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.
    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.
    devices Network devices to use.
    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.

    FAQ
    如安装时提示下面的问题
    configure: error: ncurses library or development files not found. ncurses is required for nload.
    make: *** No targets specified and no makefile found. Stop.
    make: *** No rule to make target `install’. Stop.

    用 yum install -y ncurses-devel 即可解决
