•Monitoring and Observability (blog post) •Observability — A 3-Year Retrospective (blog post) •Distributed Systems Observability (book) "[…] I tried all of these tools and more, and none of them helped resolve system performance and reliability. Let me repeat: none of them did what they claimed to do. This isn’t because they lied or misrepresented themselves, it’s because the kinds of systems we were building were fundamentally different than the systems those tools were developed to understand. Parse was an early adopter of a lot of trends which are still relatively cutting edge, and more and more people are now experiencing the consternation and frustration that I did during that time. These older tools, once revolutionary, simply no longer work for our current systems." - Charity Majors
