NTopNG - A Free, Open Source, Self Hosted, Network Monitoring and Analysis Tool.

NTOPNG (I pronounce it N-Top-N-G) is a browser based server application you can run in Docker. By setting it up properly, it can scan your entire network and provide analytical data back about traffic patterns adn levels from different machines or sub-networks within your network.

Whether you're an IT admin, or an at-home self-hoster, viewing, analyzing, and understanding your network traffic patterns can help keep your networks more secure by detecting anomolies and potential intrusion quickly, as well as helping to close security gaps.

It's crazy how much better the community edition is. If you don't force the community mode, CPU Idle was at 60%+ and accessing the site was constantly 100%.

Excellent application. Thank you. Note to add: Enable selected port in server firewall.

I just installed on my Ubuntu Server last night and so far, I am really impressed with it... Thanks AOS for making this video...

[IBRACORP]

Great video! Really like the interface and the granular drill down on data. Definitely can see this as a good solution when running multiple containers in a homelab.
Thanks for sharing

yes, I succeeded on my RPI4 in Docker. Two errors needed to be resolved. First observation was an error which indicated that the image is not running on RPI4 (ARM64 Ubuntu). So I switched to jonbackhaus/ntopng image. However also this image resulted into an error. This error did I track down to a bug in Ubuntu of which a workaround exists. Using the --dont-change-user command in the yml file did the trick. It's now working fine. :-)

AWESOME as always! Very good work and a useful tool for any professional IT person. Thank you very much.

[MehrdadGivehchi]

Your videos are simply Awsome!!!! Many thanks.

[ahmad]

This was the first tool i used in my begin, i love this tool, this tool helped me to solve many issues in my network

[omarchiguer]

Just stumbled on your channel… Great content.. Thank you, Sir!

[berndeckenfels]

Use the -br(ief) option to „ip s a“ to prune that output down when you look for interfaces

[geogmz]

It's a shame that Nprobe-NG is not part of the Community edition.. I could send my Netflow data from my Mikrotik routers to it. I guess I'll keep using PRTG for my home net.

[fossdom]

It’s available as a package in pfSense

[amanuelelhanan]

is your server/PC is serving as gateway? or how does others device info is showing up here? is there any SNMP or other configurations needed? Thanks

[PaPaTheGMan]

Nice looking utility. Unfortunately, it's only for x86 machines. My network contains mostly ARM machines.

[borisvokladski]

Cool video. Does NTopNG require a lot of RAM and CPU to run ? Right now I´m using ElastiFlow to monitoring my home network (approx. 15 physical units + 10 - 15 virtual machines) using netflow. But Elastiflow uses a lot of RAM (approx. 11 GB), and I´m looking for alternatives that is less RAM hungry.

[donaldwilliams]

Great video! Thanks. I tried to install it inside docker that was inside an LXC container! yeah, not so much. haha I installed docker on 22.04 VM using your info on installing docker and it worked like a charm! Thank you. I need to more with docker. I use LXC on Proxmox with great success. The updated version of this since your video is really impressive. Two thumbs up!

[NicoandLuis]

My GUI is buggy for some reason. Not sure if that's a Firefox issue.

[sendgl]

Fascinating program but got the impression it only gave info about connections with the host machine, I might be wrong on that though but guess network adapter might have to be in promiscuous mode. So much info though that one might get paranoid about what is going on 😎

[dingokidneys]

I find the output of 'ip addr show' to be way too verbose for what I usually need. I usually use the 'brief' option to cut it back to the essentials; e.g. 'ip -br a' gives me -
lo UNKNOWN 127.0.0.1/8 ::1/128
enp3s0 UP 192.168.1.11/24 fe80::a60:6eff:fed9:b0b7/64
virbr0 DOWN 192.168.122.1/24

Can you install this on a Raspberry Pi? Are there any guides for that. I have a Macbook but it’s not accessible 24/7 like the Raspberry Pi is.
