Charity Majors is the founder and CTO of Honeycomb, an observability tool that combines logs, traces, metrics, and all the relevant data about the production state of your application into a single dataset that can be explored in one place. Charity tells Beyang about how Honeycomb derives its definition of observability for software systems from its original definition in control theory, and how observability differs from monitoring and logging. She shares war stories from her time keeping systems online at Facebook and Parse, gives her predictions about how the landscape of observability and monitoring tools will evolve, and discusses how developer tools can make programming more accessible to everyone.
