5 Modern VnStat PHP Replacements for Bandwidth Monitoring

Network bandwidth monitoring is essential for system administrators to track data usage, analyze traffic patterns, and optimize network performance.

VnStat PHP has been a popular choice due to its simple web-based interface, but it lacks modern features like real-time monitoring, deep packet inspection, and advanced visualizations. Moreover, it is no longer actively maintained, making it less suitable for modern network monitoring needs.

If you’re looking for powerful, modern alternatives, this guide covers the top five best replacements for VnStat PHP that provide better insights, interactive dashboards, and enhanced reporting capabilities.

1. Ntopng – Web-Based Traffic and Security Network Monitoring

ntopng is a powerful network traffic monitoring tool that offers complete network visibility. It gathers traffic data from multiple sources, including traffic mirrors, NetFlow exporters, SNMP devices, firewall logs, and intrusion detection systems.

Designed for cross-platform compatibility, ntopng runs on Linux, FreeBSD (including pfSense and OPNsense), macOS, and Windows.

It captures network traffic using libpcap or PF_RING (on Linux) for optimal performance. Alternatively, it can work with nProbe to collect NetFlow/sFlow data from routers and switches or with nProbe Cento to analyze high-speed 100 Gbps links in real-time.

Unlike VnStat PHP, Ntopng offers real-time network monitoring, deep traffic analysis, and an interactive web UI, making it a robust choice for modern network monitoring.

To install Ntopng on Linux, use the following appropriate command for your specific Linux distribution.

sudo apt install ntopng         [On Debian, Ubuntu and Mint]
sudo dnf install ntopng         [On RHEL/CentOS/Fedora and Rocky/AlmaLinux]
sudo emerge -a sys-apps/ntopng  [On Gentoo Linux]
sudo apk add ntopng             [On Alpine Linux]
sudo pacman -S ntopng           [On Arch Linux]
sudo zypper install ntopng      [On OpenSUSE]    
sudo pkg install ntopng         [On FreeBSD]

Access the web interface at http://localhost:3000.

2. Netdata – Real-Time Performance Monitoring

Netdata is a powerful real-time monitoring tool that provides detailed insights into network, system, and application performance by offering live metrics, interactive dashboards, and AI-powered anomaly detection.

Netdata supports auto-detection of system components, low-latency data collection, and cloud integration for remote monitoring. The web-based interface provides second-level precision, making it ideal for troubleshooting performance issues.

With minimal resource usage, Netdata efficiently tracks CPU, memory, disk, and network activity in real-time. Its scalability and ease of setup make it a great choice for both home users and enterprises.

Netdata can be installed on most Linux distributions with a single wget or curl command:

wget -O /tmp/netdata-kickstart.sh https://get.netdata.cloud/kickstart.sh && sh /tmp/netdata-kickstart.sh
OR
curl https://get.netdata.cloud/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh

Access it via http://server-ip:19999 after installation.

3. Cacti – Scalable Network Monitoring and Graphing

Cacti is a powerful, open-source network monitoring and graphing tool designed to provide detailed insights into system performance using RRDtool for data storage and visualization.

  1. Everything works to install the vnstat, I did it previously, I got the front end installed in the web server directory but in the interface, none of the data is populated. vnstat on the command line works perfectly.

    • I have the same issue. It seems to be caused by the change in vnstat version 2.0 and newer, change to SQLite database. I don’t think the PHP frontend will work with that format as it has not been updated since 2010. I will probably have a downgrade to vnstat 1.18.

  2. On Linux Mint 17.3 only need to change this command:

    # cp -fr vnstat_php_frontend-1.5.1/ /var/www/vnstat

    into:

    $ sudo cp -fr vnstat_php_frontend-1.5.1/ /var/www/html/vnstat

    • @Michael,

      Have you installed Apache with all required modules? have you added correct settings about your interfaces in vnstat config.php file? have you opened port 80 on the firewall to access to the vnstat over web? please check these things again and let me know what error you still getting on vnstat web?
