These tools help monitor individual nodes and applications for signs of poor performance.

This article will focus on open source network monitoring tools.

If you have a live network, you need network monitoring to make sure you aren't vulnerable to an attacker. Network monitoring tools are designed for the specific purpose of monitoring network traffic and response times, while application performance management solutions use agents to pull performance data from the application stack. There are many different ways to keep tabs on a modern network. Maintaining a live network is one of a system administrator's most essential tasks, and keeping a watchful eye over connected systems is essential to keeping a network functioning at its best.
