The need for cross-service, cross-team visibility led to the creation of SRE’s golden signals. The goldens signals serve as a foundation for actionableDevOps monitoringand alerting. In a few pages, we’ll go over SRE’s four golden signals of monitoring and show why they’re such a powe...
黄金信号(Golden Signals)最初是谷歌在站点可靠性工程(SRE)实践的背景下引入的,由谷歌软件工程师Dave Rensin和Kevin Smathers在2016年O 'Reilly Velocity Conference上的一次演讲中提出,其背后的想法是提供一组关键性能指标(KPI),用于测量和监控复杂分布式系统的运行状况。 引入黄金信号是为了帮助SRE团队关注系统可靠性和...
Signals that are collected, but not exposed in any prebaked dashboard nor used by any alert, are candidates for removal. Every time the pager goes off, I should be able to react with a sense of urgency. I can only react with a sense of urgency a few times a day before I become fa...

While SREs aren’t always responsible for managing service levels, it often falls within their purview. By tracking SLIs and tying them to SLOs, you can set goals around the performance of a system. Google’s SRE book defines the four golden signals of service levels aslatency, traffic, erro...
Golden Signals帮助解决的一个问题是,我们通常只拥有少数几个服务的有用数据,而前端问题会导致对罪魁祸首的长期追捕。收集每个服务的信号有助于确定哪个服务是最有可能的原因(尤其是如果您有依赖信息),从而确定关注哪里。 就是这样。享受你的信号,因为它们既具有挑战性,也很有趣,可以发现、监控和警觉。

The four golden signals of monitoring arelatency, traffic, errors, and saturation. If you can only measure four metrics of your user-facing system, focus on these four. The time it takes to service a request. ... Therefore, it's important to track error latency, as opposed to just filte...
