Observability is a crucial aspect of software development that involves gaining deep insights into an application's behavior, performance, and user experience. Traditionally, observability has been associated with operations teams, but the shift left approach advocates for developers to actively participate in the observability process from early stages of development. This enables early issue detection, faster debugging and troubleshooting, improved collaboration, and enhanced customer experience. Lumigo is a powerful observability platform that simplifies and enhances the observability experience for developers, providing features such as distributed tracing, automated error tracking, real-time monitoring, and collaborative debugging. By shifting observability left with Lumigo, developers can create robust, reliable, and high-performance applications, ensuring their applications shine in terms of performance and user experience.
