Observability and monitoring are related concepts, but they are not the same thing.
Monitoring refers to the practice of collecting data about a system and its performance over time. This data can be used to identify trends, track changes, and detect problems. Monitoring is often used to ensure that a system is operating within certain parameters and to alert administrators when there are issues that need to be addressed.
Observability, on the other hand, is concerned with understanding what is happening inside a system by looking at its external outputs. This includes not only monitoring data, but also other types of data such as logs, metrics, and traces. Observability is focused on understanding the state and behavior of a system and identifying the root cause of problems when they occur.
In short, monitoring is about collecting data and observability is about understanding what that data means and how it can be used to improve the performance and reliability of a system.
