I can’t believe I’ve made it this long without encountering ctop (brew install ctop). What is it? Well just like top can show you general performance stats about your computer, ctop lets you see the performance of your running containers.

I found this massively helpful for figuring out where a performance issue in my application was, easily seeing that my app server was maxing out CPU while my DB was running under 20% load. Very useful tool, thanks Bradley!
