Linux服务器上监控网络带宽的18个常用命令和工具( 四 ) _带宽

安装dstat

$ dstat -nt

18. collectl
collectl以一种类似dstat的格式报告系统的统计信息；与dstat一样，它也收集关于系统不同资源（如处理器、内存和网络等）的统计信息。这里给出的一个简单例子显示了如何使用collectl来报告网络使用/带宽。

$ collectl -sn -oT -i0.5

10:32:02 3 28 9 44
10:32:02 5 42 96 96
10:32:03 5 48 3 28

安装collectl

# Ubuntu/Debian用户
$ sudo apt-get install collectl
#Fedora
$ sudo yum install collectl

上述几个使用方便的命令可以迅速检查Linux服务器上的网络带宽使用情况。不过，这些命令需要用户通过SSH登录到远程服务器。另外，基于Web的监控工具也可以用来实现同样的任务。
ntop和darkstat是面向Linux系统的其中两个基本的基于Web的网络监控工具。除此之外还有企业级监控工具，比如nagIOS，它们提供了一批功能特性，不仅仅可以监控服务器，还能监控整个基础设施
