SRE’s Golden Signals are four key metrics used to monitor the health of your service and underlying systems. We will explain what they are, and how they can help you improve service performance.

When Blameless started in 2018, the team set out on a mission to help all engineers achieve reliability with less toil and risk. Three years in, that mission has become more important than ever. What has changed is the rate of SRE adoption, now the fastest growing team and practice inside engineering. This represents a clear recognition of the many upsides that an SRE practice brings with its combination of continuous learning, velocity, and resilience.

Wondering what the difference is between observability and monitoring? In this post, we explain how they are related, why they are important, and some suggested tools that can help. The difference between observability and monitoring is that observability is the ability to understand a system’s state from its outputs, often referred to as understanding the “unknown unknowns”.

Do blameless retrospectives (or postmortems) help your team? We will explain what they are, if they really work, and how to do them right. A blameless postmortem (or retrospective) is a post-incident document that helps teams figure out why an incident happened, and brainstorm how to improve the process to prevent similar incidents from happening again. In most engineering organizations, everyone agrees that in complex systems, failure is inevitable.

Error Budgets That Work for You. Plus Support for New Relic Metrics and NR Query Language Did you know that error budget policy is the key to making SLOs actionable? In fact, Twitter’s engineering team did not successfully adopt SLOs until they introduced error budgets. SLOs enable teams to quantify customer happiness, and error budgets enable teams to make data-backed tradeoffs between reliability and feature velocity. We believe that teams optimizing for reliability must adopt both.

We’ve always advocated that every company can benefit from a blameless culture . Fostering a blameless culture can profoundly boost your organization in powerful ways, from employee retention to developer velocity and innovation. However, there’s an elephant in the room when we talk about blamelessness with executives: accountability. When things go wrong, people still need to get fired, right?
