NetHogs是一款开源的命令行工具，类似于Linux的top命令，它能实时地按进程统计网络带宽使用情况。与大多数工具不同的是，NetHogs不是按协议或子网划分流量，而是按进程进行带宽分组。这款工具无需特殊内核模块即可运行，当发生网络拥堵时，用户可以迅速定位到导致拥堵的进程PID，并及时采取措施。
什么是NetHogs?
NetHogs 是一个开源的命令行工具(类似于Linux的top命令),用来按进程或程序实时统计网络带宽使用率.
NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to indentify programs that have gone wild and are suddenly taking up your bandwidth.
NetHogs是一个小型的net top工具,不像大多数工具那样拖慢每个协议或者是每个子网的速度而是按照进程进行带宽分组.NetHogs不需要依赖载入某个特殊的内核模块. 如果发生了网络阻塞你可以启动NetHogs立即看到哪个PID造成的这种状况.这样就很容易找出哪个程序跑飞了然后突然占用你的带宽.
NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most such tools do, it groups bandwidth by process - and does not rely on a special kernel module to be loaded. So if there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this, and if it's some kind of spinning process, kill it.
Nethogs 是一个终端下的网络流量监控工具，它的特别之处在于可以显示每个进程的带宽占用情况，这样可以更直观获取网络使用情况。它支持 IPv4 和 IPv6 协议、支持本地网卡及 PPP 链接。
有很多适用于Linux系统的开源网络监视工具.比如说,你可以用命令iftop来检查带宽使用情况. netstat用来查看接口统计报告,还有top监控系统当前运行进程.但是如果你想要找一个能够按进程实时统计网络带宽利用率的工具,那么NetHogs值得一看.
