SRE (Site Reliability Engineering) monitoring is a crucial practice that focuses on ensuring the reliability and performance of software systems. It involves collecting and analyzing key metrics, logs, and traces to gain deep insights into system health. SRE monitoring goes beyond simply detecting failures; it aims to proactively identify potential issues, measure service-level indicators (SLIs), and track progress against service-level objectives (SLOs). This approach emphasizes automation, observability, and data-driven decision-making, enabling SRE teams to maintain high availability, optimize performance, and continuously improve the resilience of their systems. Key aspects of SRE monitoring include the use of the "four golden signals" (latency, traffic, errors, and saturation) and the implementation of robust alerting and incident response processes.
