PS-MRTG

Free Download PS-MRTG for Windows PC. It is a lightweight real-time network bandwidth monitoring tool that displays interface traffic through an interactive offline HTML dashboard.

Overview of PS-MRTG

Keeping an eye on network traffic is important for both home users and IT professionals. This software makes that task simple by providing live bandwidth graphs in a familiar MRTG-style layout. Built entirely in PowerShell, it runs as a single self-contained script without requiring additional software or internet access.

The tool continuously monitors network interfaces and presents upload and download activity in a clean HTML dashboard. Since everything works offline, users can safely monitor systems even in restricted environments. It supports both Windows PowerShell 5.1 and PowerShell 7+, making it a flexible choice for different Windows setups.

Real-Time Bandwidth Monitoring

The software captures network traffic in real time and updates the graphs automatically. Instead of manually checking network statistics, users can instantly see how much data is flowing through each interface.

Both incoming and outgoing bandwidth are displayed clearly, making it easy to identify traffic spikes, heavy downloads, or unusual network behavior. It feels like having a speedometer for your network that never stops working.

Classic MRTG-Style Dashboard

Many network administrators appreciate the traditional MRTG layout because it is simple and easy to understand. The tool follows this classic design while adding modern interactive features that improve the viewing experience.

The dashboard runs entirely in HTML, allowing users to open it in any modern web browser without installing extra plugins. Navigation is smooth, and the graphs remain responsive even during continuous monitoring.

Multiple Time-Based Graphs

One of the strongest features is its ability to display traffic over different time periods. Instead of showing only live activity, the dashboard automatically organizes information into four useful views.

Users can switch between live, hourly, daily, and weekly graphs with a single click. This makes it easy to compare current usage with previous activity and identify long-term bandwidth patterns.

Fully Offline Operation

The software works completely offline, making it suitable for secure environments where internet access is limited or unavailable. All monitoring, graph generation, and dashboard updates happen locally on the computer.

This approach also improves privacy because network statistics never leave the system. Everything remains under the user's control while still providing professional-quality monitoring results.

Interactive HTML Dashboard

The dashboard is designed for convenience. Instead of reading long lists of numbers, users can understand network performance through colorful graphs and organized statistics.

Because it is generated as standard HTML, the dashboard opens quickly in any browser and can easily be shared across local systems if needed. Navigation remains smooth even when multiple interfaces are being monitored.

Alarm Threshold Support

Unexpected traffic spikes can indicate heavy downloads, system updates, or even suspicious network activity. The software includes an alarm threshold feature that helps users immediately notice unusual bandwidth usage.

By setting custom limits, administrators can quickly recognize when network traffic exceeds normal levels. This saves valuable time and allows faster troubleshooting before small problems become larger ones.

HTML Snapshot Export

Sometimes users need to save monitoring results for future reference or share them with colleagues. The built-in HTML snapshot export feature makes this process incredibly simple.

With just a few clicks, the current dashboard can be saved as a standalone HTML report. Since everything is stored locally, the exported file remains portable and easy to archive.

Single Self-Contained PowerShell Script

Unlike many monitoring tools that require installers, services, or multiple components, this solution is delivered as a single PowerShell script. Installation is minimal, making deployment extremely fast.

The software has no external dependencies, reducing compatibility issues and simplifying maintenance. Users can simply run the script and begin monitoring their network almost immediately.

Broad PowerShell Compatibility

Compatibility is another major advantage. The tool works with Windows PowerShell 5.1 as well as modern PowerShell 7 and newer versions. It is also fully compatible with ConstrainedLanguage mode, making it suitable for highly secure Windows environments.

This flexibility allows organizations to use the same monitoring solution across different systems without worrying about major configuration changes.

Simple, Lightweight, and Reliable

Many monitoring applications consume significant system resources, but this one stays lightweight while delivering accurate bandwidth information. Since it uses native PowerShell capabilities, performance remains efficient even during extended monitoring sessions.

Its straightforward design makes it suitable for beginners while still providing the functionality experienced administrators expect from a professional bandwidth monitoring utility.

System Requirements

• Operating System: Windows 11 / 10 / 8.1 / 7
• Processor: Minimum 1 GHz Processor (2.4 GHz recommended)
• RAM: 2GB (4GB or more recommended)
• Free Hard Disk Space: 200MB or more is recommended

Conclusion

PS-MRTG is a practical and lightweight network bandwidth monitoring solution for Windows users who need real-time traffic visualization without unnecessary complexity. It combines live monitoring, classic MRTG-style graphs, offline HTML dashboards, multiple time views, alarm thresholds, and snapshot export into a single PowerShell script. Whether you manage a personal computer or an enterprise network, it provides an efficient way to monitor bandwidth with minimal setup and reliable performance.
