Why you need to monitor the four golden signals
Blog post from New Relic
Application performance monitoring (APM) and site reliability engineering (SRE) benefit significantly from tracking Google's four golden signals: latency, traffic, errors, and saturation, as they provide essential insights into application health. Latency measures the time taken to complete requests, traffic quantifies the number of requests, errors track failed requests, and saturation gauges the system's load capacity. New Relic offers a streamlined approach to monitoring these signals by allowing users to create dashboards and alerts, which help detect and address issues proactively. The platform includes features like pre-built dashboards, alerts, and the Lookout tool for a comprehensive view of an application's performance, ensuring enhanced observability and reliability. Users can customize these tools to better fit their specific needs, and New Relic facilitates easy setup with a free account and guided installation processes, highlighting its commitment to improving application monitoring practices.
