This article mainly explains "how to use linux monitoring software". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to use linux monitoring software.

Linux monitoring software includes: 1, Monit, for program and service monitoring; 2, NetHogs;3, Monitorix;4, Arpwatch;5, Suricata;6, VnStat PHP;7, Nagios;8, Nmon;9, Collectl and so on.

The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

9 common Linux performance monitoring tools

1. Monit-Monitoring of programs and services

This is a free and open source Web-based program for automatic monitoring and management of system processes, programs, files, directories, permissions, and verification file systems. The services it monitors include Apache, MYSQL, Mail, FTP, Nginx, and so on. The system status can be viewed from the command line or from its own network interface.

2. NetHogs-monitors the network bandwidth of each process

NetHogs is a beautiful open source Mini Program (similar to the top command on Linux) that keeps each process online active on your system. It also maintains the real-time network traffic bandwidth usage of a program or application.

3. Monitorix-system and network monitoring

Monitorix is a lightweight monitoring tool on Linux/Unix as much as possible, mainly designed to monitor running systems and network resources. It has a built-in HTTP web service to collect system and network information on a regular basis and display it as pictures. It can monitor the system's average load usage, memory allocation, disk drives, system services, network ports, mail statistics (Sendmail, Postfix, Dovecot, etc.), MYSQL databases, and more. Its main purpose is to monitor the performance of the whole system, and help to monitor faults, bottlenecks, abnormal activities and so on.

4. Arpwatch-Ethernet activity monitor

Arpwatch is a program used to monitor the address resolution (network address translation) of Ethernet network traffic in Linux networks. It has been monitoring Ethernet traffic and the IP and MAC address pairs that generate logs as the network timestamp changes. When an IP address or MAC address pair changes, it sends an email to notify the administrator.

And it is very useful in detecting ARP attacks.

5. Suricata-Network Security Monitoring

Suricata is a high-performance open source monitoring tool for network security and intrusion detection and prevention operating systems such as Linux, FreeBSD, Windows and so on. It is owned by a non-profit fund, OISF (Open Information Security Foundation).

6. VnStat PHP-Monitoring network bandwidth

VnStat PHP is the most popular social tool for Web front-end applications called "vnstat". VnStat PHP uses a good graphical mode to monitor the use of network traffic. It shows network traffic usage in hourly, daily, and monthly summary reports.

7. Nagios-Network / Server Monitoring

Nagios can monitor remote Linux, Windows, switches, single-window routers and printers. It can show critical alarms on your network and server and help you solve the problem before the error comes back.

8. Nmon-monitors the performance of Linux system

This tool has two modes: online mode and capture mode. The online mode is suitable for real-time monitoring, and the capture mode is used to store the processing after output to CSV format.

9. Collectl-Integrated performance testing tool

Collectl is another powerful command-line-based monitoring tool that can be used to collect information about system resources, including CPU usage, memory, network, nodes, processes, NFS, TCP sockets, and so on.
