Open Source Linux System Monitoring Tools

Network Security Toolkit (NST) is a bootable ISO image (Live USB Flash Drive) based on Fedora 44 providing easy access to best-of-breed Open Source Network Security Applications and should run on most x86_64 systems. The main intent of developing this toolkit was to provide the security professional and network administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 125 Security Tools by INSECURE.ORG are available in the toolkit. An advanced Web User Interface (WUI) is provided for system/network administration, navigation, automation, network monitoring, host geolocation, network analysis and configuration of many network and security applications found within the NST distribution. In the virtual world, NST can be used as a network security analysis, validation and monitoring tool on enterprise virtual servers hosting virtual machines.

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers, but due to its simplicity and small size can be used on embedded devices as well. It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Monitorix includes its own HTTP server built in (which is listening by default on port 8080/TCP) to see the statistics graphs, so you aren't forced to install a third-party web server to use it. Just point your browser at http://localhost:8080/monitorix.

OpenSMART, the Open (System|Source) Monitoring And Reporting Tool, is a Open Source System Monitoring Software to monitor problems on your servers and to report some important data about your servers. It is somehow similar to Tivoli or OpenView.

PortAlert continuously checks TCP ports on servers, network devices, databases, web services, and applications, and sends alert notifications when a service becomes unavailable or is restored. When ports time out, additional 3 PING host response results are included in the alert text (helps identify network vs application issues). PortAlert is working in multi-threaded workers to monitor targets in parallel, it designed for small and medium businesses that need simple monitoring without the complexity of enterprise monitoring platforms. Microsoft teams + Telegram + Email alerts Common monitored services include: • HTTP (80) • HTTPS (443) • MySQL (3306) • Microsoft SQL Server (1433) • PostgreSQL (5432) • Oracle Database (1521) • DNS (53) • SMTP (25, 465, 587) • SFTP / SSH (22) • FTP (21) • LDAP (389) • RDP (3389) • Self-Defined Port Number Download: https://www.smartbooth.com/download.htm License: https://www.smartbooth.com/license.htm

gtop is a tool that helps you monitor your systems through a dashboard user interface, and it is optimized to monitor and visualize terminals. gtop requirements are to have Node.js version 8 or higher. It supports Linux, OSX, and Windows (with partial support). You need to assign host net and pid to access the metrics in the host machine. Start gtop with the gtop command. To stop gtop use q, or ctrl+c in most shell environments. You can sort the process table by pressing 'p' for Process Id, 'c' for CPU usage, and 'm' for Memory usage. If you see question marks or other different characters, try to run it with the environment variables provided in the documentation. gtop is released under the MIT license.
