linux網(wǎng)絡(luò)流量實(shí)時(shí)監(jiān)控工具之nload

[我的Linux,讓Linux更易用]個(gè)人覺(jué)得nload是個(gè)很好用的一個(gè)工具,功能也很強(qiáng).只是相對(duì)單一,只能查看總的流量,不能像iptraf那樣,可針對(duì)IP,協(xié)議等
可以實(shí)時(shí)地監(jiān)控網(wǎng)卡的流量,分Incoming,Outgoing兩部分,也就是流入與流出的流量
同時(shí)統(tǒng)計(jì)當(dāng)前,平均,最小,最大,總流量的值,使人看了一目了然,如下圖

安裝
wget http://www.roland-riegel.de/nload/nload-0.7.2.tar.gz
tar zxvf nload-0.7.2.tar.gz
cd nload-0.7.2
./configure;make;make install

使用
直接用nload回車即可,也可以指定網(wǎng)卡,如nload eth1
還可以指定是以K或M來(lái)顯示流量,如nload -u M顯示的流量是以MB為單位的

Command line syntax:
nload [options] [devices]
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

FAQ
如安裝時(shí)提示下面的問(wèn)題
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 即可解決
