## AI overview

The article explains the Four Golden Signals--latency, traffic, errors, and saturation--as a framework for monitoring application health and performance. It describes how SRE teams can correlate these signals to investigate problems, plan capacity, and guide alerting, and compares the framework with RED and USE. It also discusses data sources, monitoring tools, anomaly detection, chaos engineering, and synthetic monitoring.
