We now know some ways to optimize our Docker deployments. We also know how to scale to improve performance. But how do we know that our tuning assumptions were correct? Being able to monitor our Docker infrastructure and application is important to figure out why and when we need to optimize. Measuring how our system is performing allows us to identify its limits in order to scale and tune accordingly.
In addition to monitoring low-level information about Docker, it is also important to measure the business-related performance of our application.
