please see here https://github.com/aparcar/packages/tree/batadv-vis-exporter

if you provide a node within a batadv setup with the current snapshot installed & grant me access I'll test the code and create a PR for upstream

@alfinal did you have the time to check the plugin?

[alfinal]

We're on it! I suppose that we're going to install our own prometheus server.

Sweet!

Did this go anywhere? My group is looking at deploying libremesh networks as emergency coms in a nonprofit manner at events for harm reduction, and using rcmesh looks up our alley, hoping it can visualize the layer 2 batman parts of the mesh and not just the layer 3 bmx nodes if I'm understanding this correctly.
