Monitoring packet loss, jitter, and net speed with UI

Posted by filisterr@reddit | linuxadmin | View on Reddit | 6 comments

I am living in an 85 sq.m. apartment and using MoCA router to get my Internet, but my wireless network is very unstable and I often have occasional packet loss and high jitter. I have connected my cable router to eero 6 router and I am using the eero 6 along with one satellite unit to distribute the Internet, as the signal at my desktop is pretty weak.
I am having a Raspberry Pi4 connected directly over LAN cable to the MoCA router and was thinking of continuously monitoring the network speed, packet loss, and jitter from it.

I can also write my own scripts and save the results in a CSV file and then use pandas to convert the CSV file into a dataframe and analyze it, but I was wondering if there is an easier solution with already built-in graphs, etc.

In the worst case, I will write my own Streamlit UI.

Sounds like you might be having WiFi rather than throughput issues. Have you set the channels manually and/or are you using DFS channels perhaps, that are subject to going down when they detect radar?

I don't have any control over the WiFi channels. Yes, I understand that my problem might be from the WiFi signal, and that's what I am trying to figure out, whether it is from the provider or from the Wifi. The Raspberry is connected over cable, so if I don't see any packer loss or jitter on the MoCA, then it is a problem with the WiFi. Otherwise I need to bug the ISP.

Use MTR to monitor whatever you are having a problem with.

It measures loss to each hop along the network path.

If there is packet loss to the first hop, it's your local network.

Does it measure jitter?

If you just need a simple GUI to view performance data for a host, cockpit does a nice job of it.

I think it needs one extra package to record historical data (cockpit-pcp), see this guide. Aside from that, it is largely plug-and-play. It uses many common tools on the back-end, so it doesn't try to reinvent the wheel.

Cockpit is developed mostly by redhat, but it is available for most Linux distributions.
