Summary
In this chapter, we learned how monitoring can help us to visualize data at the edge, especially how to visualize data that comes from sensors, and how to build a basic use case scenario to extend for production use cases. To build this system, we used Prometheus as our time series database, Mosquitto as our basic way to store data from sensors, and Redis as a temporary queue to prevent the loss of our data from sensors. We also practiced how to build an edge computing system, using its different layers from the far edge to the cloud layer. This shows how important time series databases can be to manage sensor data and how tools such as Grafana can help to visualize it. This scenario can also be extended to farming, ocean and sea monitoring, animal populations, and so on. In the next chapter, we are going to continue with a similar scenario but applied to GPS and reading sensor data at long distances.
