📄️ What is Observability?
Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. It helps to understand the behavior of a system by analyzing its outputs. Observability is a key concept in the field of control theory, which is the study of how to control systems. It is also a key concept in the field of systems engineering, which is the study of how to design and manage systems.
📄️ Monitoring
Monitoring is the process of observing and tracking the performance of a system. It is a critical part of maintaining the health and reliability of a system. Monitoring can be used to detect and diagnose problems, and to ensure that a system is performing as expected.
📄️ Logging
Logging is the process of recording events that occur in a system. It is a critical part of observability, as it provides a record of what has happened in a system. This record can be used to understand the state of the system, diagnose problems, and monitor performance.
📄️ Tracing
Tracing is the process of tracking the flow of requests through a distributed system. It is a critical part of understanding the performance and behavior of a system, and is used to diagnose and debug problems. Tracing can be used to identify bottlenecks, latency, and errors in a system, and to ensure that a system is performing as expected.
📄️ Profiling
Profiling is the process of analyzing the performance of a system to identify bottlenecks and areas for optimization. Profiling can be used to identify performance issues, such as slow response times, high CPU usage, and memory leaks. Profiling tools can be used to collect data about the performance of a system, and to analyze that data to identify performance issues.
