Chrome Devtools is used by all web developers to debug and inspect network traffic. Sometimes the page loads sluggishly, and then you open Devtools and reload the page, and the problem is gone. What if you wanted to know how well the site performs, for example, when you click six pages? While it is possible to keep the tab open at all times, it is hard to see the big picture from the data in the network tab. This is a wonderful use case for time series and Grafana! In this presentation I will show how to get the same data visualized in Grafana in near real time (1s delay) without opening the Devtools at all.
