The Four Golden Signals – latency, traffic, errors, and saturation – are essential insights for understanding the health and performance of modern cloud applications. Originating from Site Reliability Engineering (SRE) practices at Google, these signals help interpret complex observability data, allowing SREs to improve system reliability, perform root cause analysis, optimize performance, and enhance user experience. Various monitoring tools, including infrastructure monitoring, APM, and synthetic monitoring, are utilized to measure these signals effectively. The methodology contrasts with other frameworks like RED and USE, offering a comprehensive approach to performance management.
