observability
n.n. the ability to understand how a complex system is working by looking at the data it produces. In computing, it helps engineers find and fix problems by watching signals like logs and performance charts.
n. the extent to which the internal state of a system can be inferred from knowledge of its external outputs. In software engineering, it involves collecting and analyzing logs, metrics, and traces to monitor health and troubleshoot performance issues.
Good observability helps us find bugs quickly.
The team improved the application's observability by adding detailed logging and real-time performance dashboards.
Modern microservices architectures require high observability to ensure that developers can trace a single request across dozens of independent services to identify the root cause of a failure.
Commonly used in control theory and software engineering; often paired with 'system' or 'application'.
