Observability refers to the ability to measure and understand how an application is operating in real-time.In order to achieve observability, it is critical to set up appropriate metrics, monitoring, and logging for the application.Collecting historical data is crucial to analyzing progress and validating the training plan.Observability helps teams make informed decisions about how to improve and plan for the future.It is important to set service-level objectives (SLOs) and define penalties for when they are not met in order to maintain consistent performance.Profiling and performance measurements are important aspects of observability and can help identify problems and find root causes.Shared responsibility for observability can help delegate responsibilities outside of the team and provide valuable feedback.It is also important to avoid storing too much data in the dashboards, as it can lead to noise and a loss of service visibility.Observability is a continuous process and requires ongoing attention to ensure accurate metrics and optimal performance.Ultimately, observability is critical for maintaining healthy and productive applications.
