This article mainly shows you the "Linux tool Nethogs by process monitoring network bandwidth example analysis", the content is easy to understand, well-organized, hope to help you solve your doubts, the following let the editor lead you to study and learn the "Linux tool Nethogs by process monitoring network bandwidth example analysis" this article.

NetHogs is a small net top tool that groups bandwidth by process instead of slowing down each protocol or subnet as most tools do. NetHogs does not rely on loading a particular kernel module. If there is a network congestion, you can start NetHogs and immediately see which PID caused the situation. This makes it easy to find out which program runs away and suddenly takes up your bandwidth.

In a nutshell, you can view the traffic of processes under linux through nethogs.

Installation and deployment

1. Compile and install the nethogs dependent package. There is no package for nethogs in the centos default rpm repository, so we need to compile manually. Nethogs compilation depends on 2 libraries, which need to be installed before compilation

# yum install libpcap libpcap-devel gcc* ncurses*

2. Download nethogs

Since bug (creating socket failed while establishing local IP-are you root?) exists in 0.8, version 0.81 is used here.

# wget-c https://github.com/raboof/nethogs/archive/v0.8.1.tar.gz

3. Compile and install

# tar-xvf v0.8.1.tar.gz # cd nethogs-0.8.1/ # make & & make install

# the default path after installation is / usr/local/sbin/nethogs

4. Test run:

# nethogs

Usage

1. Command line parameters

2. Example:

Instance 1: refresh every 5 seconds, specify refresh rate # nethogs-d 5 instance 2: monitor eth0 network bandwidth # nethogs eth0 instance 3: monitor both eth0 and eth2 interfaces # nethogs eth0 eth2

3. Interactive commands:

Here are some interactive commands (keyboard shortcuts) for NetHogs

M: modify unit

R: sort by traffic

S: sort by send traffic

Q: exit command prompt
