linux網絡流量實時監控工具之nload

linux網絡流量實時監控工具之nload

[個人Linux,讓Linux更易用]我的以爲nload是個很好用的一個工具,功能也很強.只是相對單一,只能查看總的流量,不能像iptraf那樣,可針對IP,協議等
能夠實時地監控網卡的流量,分Incoming,Outgoing兩部分,也就是流入與流出的流量
同時統計當前,平均,最小,最大,總流量的值,令人看了一目瞭然,以下圖

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回車便可,也能夠指定網卡,如nload eth1
還能夠指定是以K或M來顯示流量,如nload -u M顯示的流量是以MB爲單位的

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.

FAQ
如安裝時提示下面的問題
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 便可解決
