Open Source JavaScript 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.

NagVis is a visualization addon for the well known network managment system Nagios. NagVis can be used to visualize Nagios Data, e.g. to display IT processes like a mail system or a network infrastructure.

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.

CodeCampus OS is a custom Linux distribution based on Ubuntu 24, designed for beginner developers, computer science students, and self-learners who want to start coding without friction. Unlike traditional setups that require hours of installation and configuration, CodeCampus provides a fully pre-configured, learning-first environment right out of the box. From the moment you boot, everything is ready—so you can focus on learning, experimenting, and building instead of troubleshooting. CodeCampus solves this by removing setup complexity and providing a ready-to-use development environment that lets you start coding immediately. 👉 Getting started guide: https://codecompasss.github.io/code_campus_userguide/getting-started/

ACGVision is a software monitoring system developped in Java and using SOAP WebServices.

Andutteye is an open source systems management platform that automates enterprise data centers and keeps them running. With Andutteye you can control your Linux and Unix system from a central point of operation.

Fleetbase is a comprehensive, open-source platform for the management and orchestration of logistics and supply chain operations. This dual-natured platform serves not only as an efficient operational tool for companies within these industries but also as a robust foundational layer for developers. Its versatility emanates from its core, which is skillfully constructed around a series of "extensions," creating a flexible and customizable framework that accommodates a wide spectrum of supply chain and logistics requirements. Every individual extension within Fleetbase is purposefully engineered to fulfill specific roles within the expansive ecosystem of supply chain and logistics. With inherent extensibility users have the freedom to craft their own extensions, thereby expanding the ecosystem and ensuring the platform's adaptability across a multitude of use cases.

Hyperic is application monitoring and performance management for virtual, physical, and cloud infrastructures. Auto-discover resources of 75+ technologies, including vSphere, and collect availability, performance, utilization, and throughput metrics.

JointJS is the open source HTML 5 JavaScript diagramming library. JointJS is a comprehensive framework for building fully interactive diagramming tools and application builders. JointJS makes it easy to create visual languages & tools of various kinds. The event-driven nature together with MVC architecture of JointJS makes it easy to plug-in any backend application. Whether you're creating a state machine builder, modeling tool, voice application designer, system monitoring tool, electronic circuits simulator, information system browser and editor, implementing a visual programming language or building a graph visualization with interaction, JointJS is the toolkit that makes your life easier.

Mimic is a visual web-based monitoring aggregation system aimed at sysadmins managing medium to large server farms which reduces status of hosts to a small icon representing each host. It could also be thought of as a monitoring system monitoring system. This project was moved to GitHub in May 2015 and active development no longer happens here.

nodejs-dashboard is a terminal-based telemetry dashboard that provides real-time insight into Node.js application behavior during development. It overlays an interactive monitoring interface on top of a running Node process, displaying metrics such as event loop activity, memory usage, and request throughput. The tool can be injected into applications with minimal or no code changes by using Node’s preload flag, making adoption straightforward for developers. Its interface uses Unicode Braille characters to render compact graphs directly in the terminal, creating a highly responsive visual experience. nodejs-dashboard is primarily aimed at local development and debugging rather than production observability, helping engineers quickly identify performance bottlenecks. Although the repository is now archived, it remains a useful lightweight option for developers who prefer terminal-native telemetry during Node.js development workflows.
