Summary
In this chapter, we saw how we can get real-time statistics on our running containers and how we can use commands that are familiar to us, to get information on the processes that are launched as part of each container.
On the face of it, docker stats seems like a really basic piece of functionality that isn't really anything more than a tool to help you identify which container is using all the resources while a problem is occurring. However, the Docker command is actually pulling the information from a quite powerful API.
This API forms the basis for a lot of the monitoring tools we will be looking at in the next few chapters.
