NAS-based tool for detailed network traffic monitoring

[BijanK]

I am looking for a (Synology-based) tool (package?) that would allow me to precisely monitor in- and outgoing network traffic from and to the NAS. I would, for instance, like to know how much traffic is going in and out right now for the individual packages installed.

Do you know of any such tool?

Thanks!

I would be very interested in the answer to this

Good question. I will follow this thread to see if anyone comes up with something.

There might be something in the community packages.

For interface bandwidth monitoring I run PeakHour 4 on Mac and it uses SNMP to track my NASs, switch, router, and Macs.

answer:

NtopNG - docker container

Deployed and tested NtopNG container First touch feelings: 1. running w/o a significant impact on NAS host (it was my worries) 2. Useful to fast preview of the network status before you will use Wireshark 3. you can create pools for a clustered preview or exact host interface flow check 4...

OFC it's a Community version (free), but you can purchase a Product Key to unlock more features when you need some of them (no need).

I use GIT stack to monitor all my NAS network activities via Grafana in real-time, but not per package that OP is asking for.

Guess netData would be a solution for this but again not really clearly listing the apps, but close.

Installed NTOP as per Marius Bogdan's instructions. It works and does indeed seem to offer a ton of options. However, it also seems to take quite some memory and CPU%. For now, I have stopped the container, but will have a look at it at some later date.

Each Syno package has defined default port(s) for a communication

What network ports are used by DSM services? - Synology Knowledge Center

Synology Knowledge Center offers comprehensive support, providing answers to frequently asked questions, troubleshooting steps, software tutorials, and all the technical documentation you may need.

then you can define filters to capture this communication at the packet level also

rest of them you can get by iptables or capture by tcpdump = then you can upgrade your filters in the Ntopng
