How to implement NetJSON in OpenWisp

[Hugo Zárate]

Well, I have OpenWisp installed on Ubuntu and I registered a Router that contains OpenWRT.

I want to use Network Topology Visualizer but I don't understand well how to do it.

In my playbook file I enabled this option -> openwisp2_network_topology: true

I created a Topology and I selected the same Organization that I have in my device.

But I'm not pretty sure what's next.

Basically, I need to know or see something that tells me if my router has been disconnected or turned off, for example.

Can anyone give me some advice? Or any information, please?

The network topology module is mainly designed for mesh networks, but can work also with OpenVPN if you use a management VPN.

In that case, you can create a topology, use receive strategy, setup your VPN to write the status file somewhere and have a cronjob send its data to the receive URL periodically (say every 3 minutes).

That way you would now if any device lost its connection to the internet or to the VPN.

Best regards
