linux网络流量实时监控工具之nload
[我的Linux,让Linux更易用]个人觉得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,如下图
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
Debian: apt-get install -y libncurses5-dev
安装
tar zxvf nload-0.7.4.tar.gz
cd nload-0.7.4
./configure;make;make install
使用
直接用nload回车即可,也可以指定网卡,如nload eth1还可以指定是以K或M来显示流量,如nload -u M显示的流量是以MB为单位的看看还有哪些参数或选项
