This is all great, what's the catch?
So you are maybe thinking to yourself that all of this information available in your browser is really useful; being able to see real-time performance metrics in an easily readable format is a really plus.
The biggest drawback of using the web interface for cAdvisor, as you may have noticed, is that it only shows you one minute's worth of metrics; you can quite literally see the information disappearing in real time.
As a pane of glass gives a real-time view into your containers, cAdvisor is a brilliant tool; if you want to review any metrics that are older than one minute, you are out of luck.
That is, unless you configure somewhere to store all of your data; this is where Prometheus comes in.
