Everything, Everywhere, All At Once

Steve Cunnew, a Technical Success Manager at New Relic, shares insights from his 25 years of experience in observability and customer experience, emphasizing the critical importance of monitoring all components of an application or service, regardless of perceived significance. He recounts an experience with a performance issue in a financial services application, where the root cause was traced to an unmonitored file server, highlighting the necessity of comprehensive monitoring to avoid blind spots. Cunnew stresses that observability's primary goal is to provide insight into application behavior and performance, allowing for quick resolution of errors and performance degradations. He advises collecting extensive data on infrastructure and services to identify potential impacts on applications and suggests maintaining historical data to reduce the Mean Time to Resolution (MTTR) of issues. While his views represent personal insights rather than official endorsements by New Relic, he encourages readers to engage in further discussions through New Relic's Explorers Hub for additional support and questions.
