While open-source monitoring tools are indispensable in modern IT environments, organizations often grapple with the transition from anomaly detection to swift, informed action. This presentation delves deep into this challenge, offering a step-by-step guide to embedding robust incident response practices seamlessly for DevOps teams. We will dissect the incident response workflow into four tangible stages: Preparation, Response, Communication, and Learning. Attendees will leave with a practical roadmap to minimize user impact, reinforce a culture of continuous growth, and enhance their existing open-source monitoring frameworks.
