Showing network topology diagrams with quasi-live data

Network topology diagrams are very useful when you need to monitor your communication infrastructure. All IoT systems depend on IP networks, so having a clear picture of physical connections is crucial to addressing communication problems.

The interruption of data transmission from an IoT device can be related to problems in the network, for example, the loss of power in a network device, or the unplugging of a cable on an interface.

To build topology diagrams, we will use two software tools:

• The software draw.io for drawing the diagrams
• The Grafana FlowCharting plugin for showing dynamic diagrams

Let’s start with the draw.io software.

Building diagrams with draw.io

draw.io is a diagram software that you can use for free either online or locally. draw.io allows you to draw different types of diagrams, from basic forms to network topologies and mind maps.

This software offers a very broad...
