Description
The bandwidth-usage-log records how much data is transmitted and received through a device’s network interfaces over time. This file is essential in environments where bandwidth consumption must be monitored closely—whether due to ISP limits, cost concerns, or performance management.
Logs typically include timestamps, interface names (like eth0, wlan0), and byte counts for both inbound and outbound traffic. More advanced implementations may also log traffic by process ID, user, application, or protocol type, which allows deep insight into which services are consuming the most bandwidth.
In homes or small offices, this log helps avoid exceeding bandwidth caps or detect if a specific device is using too much data. In enterprise environments, it’s used to monitor overall traffic load, plan for capacity upgrades, or investigate anomalies like data spikes during off-hours (which might indicate malware or data exfiltration).
Tools like vnStat, iftop, nload, and more sophisticated network monitoring platforms like NetFlow or sFlow export this type of log data. In billing or pay-per-use systems—such as co-working spaces or hosting providers—bandwidth-usage-log is vital for metering consumption and generating invoices.
Administrators often use this log alongside firewall logs or connection-log entries to correlate usage with activity, detect unauthorized file transfers, or enforce fair usage policies. The logs can be visualized in dashboards to provide real-time and historical usage statistics.

“This bandwidth-usage-log file is incredibly useful! I’ve been struggling to keep track of my internet usage, especially with data caps. This neat piece of coding delivered exactly what it promised, providing detailed logs of sent and received data, broken down by time intervals. The per-process logging is a fantastic feature I didn’t expect and makes it easy to identify the biggest bandwidth hogs. This has already helped me optimize my network usage and avoid overage charges. A brilliant solution for anyone needing to monitor their data consumption!”
