Observability refers to the ability to understand the internal state of a system by examining its external outputs. It is a crucial concept in modern software development and operations, particularly for complex, distributed systems. The core idea is to gain insights into how a system is performing and behaving without needing to know its intricate internal workings beforehand. This is achieved by collecting and analyzing telemetry data.

Key characteristics of observability include the comprehensive collection of three primary types of telemetry: logs, metrics, and traces. Logs provide detailed, event-level records of what happened within the system. Metrics are numerical representations of system behavior over time, offering aggregated insights into performance and resource utilization. Traces capture the end-to-end journey of a request as it propagates through various services, revealing dependencies and latency issues.

Effective observability allows teams to quickly detect, diagnose, and resolve issues. It facilitates performance optimization by identifying bottlenecks and understanding resource consumption patterns. Furthermore, it supports security investigations by providing a detailed audit trail of system activity. The goal is to enable users to ask arbitrary questions about their system's behavior and receive meaningful answers, even for unforeseen problems. This contrasts with traditional monitoring, which typically focuses on predefined checks and alerts for known failure modes.
