Editor to share with you how to install and use NetHogs under Linux, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

NetHogs is a small net top tool that groups bandwidth by process rather than slowing down each protocol or subnet as most tools do. NetHogs does not need to 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 ran away and suddenly took up your bandwidth.

Install NetHogs under Ubuntu, install NetHogs under sudo apt-get install nethogsReadHat [root@localhost tmp] # rpm-ivh nethogs-0.8.0-1.el6.x86_64.rpmwarning: nethogs-0.8.0-1.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEYPreparing... # 1:nethogs # # NetHogs provides interactive control instructions: M: Cycle between display modes (kb/s, kb) B, mb) switch network speed display unit r: Sort by received.
