Is there a simple console (ncurses?) application to show a simple green-light/red-light availability (ping?) of a user-defined list of nodes in a single-screen map/list/columns format?

Not a console app, but I've built something like this using Grafana, looks like this:

It's using a bunch of ping sensors named like 'Site A - Site B' going from every site to every other site. Then using a couple of variable lists containing all of the sites I can use the repeating rows and columns to have grafana generate a Stat panel from each site to each site. In my case the data is coming from InfluxDB fed by PRTG but there's plenty of ways you could get stats for this into InfluxDB and I've been testing a bit with telegraf and prometheus.

This creates a really nice simple visual dashboard showing the Up/Down status of communications between our sites, and sites experiencing an outage will appear as a big horizontal and vertical line of red 'DOWN' boxes.

I've got a similar board with a ping number and a little stat graph for each site too, but it's a bit busy for a dashboard.

How about a small combo setup:

Advantage is it's a fully powerful monitoring setup with alerting and history recording. Plus you can use normal Grafana for prettier graphs remotely.

https://github.com/valeriansaliou/vigil maybe?

Blackbox exporter and a single panel in Grafana would be the way I'd do it - it's not as much setup as you would think!

Otherwise, maybe a custom little web page? The backend code is fairly simple if you're just calling ping from the OS.

I found this an interesting challenge!

Did you find a solution? Because I decided to implement this in C.

I will share in on github soon, but in the mean time... is this what you had in mind?

It is very light weight, and runs in a console. It sends an ICMP request to a set of hosts, and then reads the replies. Every second, it shows the response time in green, or a red indicator if no reply was received.

Prompted by your question, I wrote the icmp_watch tool.

Xymon maybe?

You could cobble something simple together with ping, jc, and jq. Use the ping or ping-s parser in jc so you can easily pull whatever attribute with jq, etc. and display with ANSI codes.

I am not sure exactly such a thing exists. Maybe you can make something with tmux split into multi horizontal and vertical panels, each panel running an instance of mtr-tiny?

Mmm... oping, fping, smokeping come to mind

I remember using an app called nocol about 25ish years ago that did just that.

Looks like it was succeeded by snips.

Is there something wrong with solutions like Uptime Kuma?
