• Real-time monitoring. DU Meter continuously displays the current data transfer speed for both downloads and uploads. The information is presented in a floating window with dynamic graphs that reflect network activity in real time.
• Detailed statistics. It collects and stores historical data on network usage. It generates daily, weekly, monthly, and yearly reports. These reports show the total volume of data transferred, maximum and average speeds, and connection times.
• Customizable alerts. Allows configuration of notifications based on various criteria. Warnings can be set when a specific speed is exceeded, when a predefined amount of data is consumed, or when the connection drops or is restored.
• Quota control. This feature sets limits on the amount of data that can be transferred during a specific period (day, week, month). The program alerts the user when approaching or reaching the configured limit, helping to avoid excess usage charges.
• Per-application measurement. Identifies and breaks down bandwidth consumption by individual processes and applications. It shows which programs are using the network connection and the amount of data each is sending and receiving.
• Connection history. Maintains a chronological record of all network sessions. For each session, it records the assigned IP address, the connection duration, and the total data transferred during that online period.
• Multiple interfaces. It is compatible with and can simultaneously monitor various types of network adapters. It works with Ethernet, Wi-Fi, PPPoE, VPN, and mobile (3G/4G/5G) connections.
• Data export. Allows saving reports and statistical data in several formats. Reports can be exported to text files (TXT), spreadsheets (CSV, XLS), or HTML documents for further analysis or archiving.
• Invisible measurement mode. Performs traffic monitoring without interfering with other activities. It operates in the background with minimal system resource consumption, ideal for long-term measurements.
• Visual customization. Offers options to adapt the appearance of the main interface. Users can change graph colors, window transparency, and its position on the screen.
• Supported protocols. Analyzes network traffic using a variety of protocols. It is compatible with TCP, UDP, ICMP and others, providing a complete view of all network activity.
• Firewall integration. It can work in conjunction with system firewalls. This integration allows for more granular traffic control and correlating security alerts with network activity.

DU Meter was developed by Hagel Technologies, a company specialized in utility software for networks and systems. Its development began in the late 1990s, with the first version officially released in 1999. The program was originally created to meet the need for a simple but accurate network traffic monitor for Windows operating systems. It is written primarily in C++, using low-level Windows APIs for precise network packet capture.
