When one service fails, the incident report may contain a recommendation such as:</p> <p>"Check the other services for the same problem."</p> <p>If this task is never completed, another service can experience the same problem later.</p> <p>The information already exists, but it is difficult for engineers to manually connect information across many old incident reports.</p> <h2> Our Solution: Faultline </h2> <p>Faultline remembers previous incidents and uses that information when a new alert arrives.</p> <p>It answers five important questions:</p> <ol> <li>Have we seen this problem before?</li> <li>Which previous incidents had the same underlying cause?</li> <li>What fixed the problem previously?</li> <li>Which other services are still exposed to the same problem?</li> <li>Did someone previously promise to fix it but never complete the task?</li> </ol> <p>This gives engineers useful historical context while investigating a new incident.</p> <h2> How It Works </h2> <p>When a new alert arrives, Faultline searches its incident memory and connects related information.</p> <p>For example, an IAM authorization failure can be connected to previous incidents that had the same underlying cause.</p> <p>Faultline can then show:</p> <ul> <li>Previous related incidents</li> <li>Common underlying cause</li> <li>Previous runbook or solution</li> <li>Other services with the same exposure</li> <li>Unfinished remediation tasks</li> </ul> <p>Instead of starting the investigation from zero, engineers receive relevant context from previous incidents.</p> <h2> Uses </h2> <p>Faultline can be used to:</p> <ul> <li>Connect new alerts with previous incidents.</li> <li>Identify repeated underlying problems.</li> <li>Retrieve previous fixes and runbooks.</li> <li>Find other services exposed to the same problem.</li> <li>Track unfinished remediation tasks.</li> <li>Provide historical context during incident investigation.</li> <li>Help engineering teams learn from previous outages.</li> </ul> <h2> Benefits </h2> <ul> <li>Reduces the need to manually read many old incident reports.</li> <li>Helps engineers identify repeated problems faster.</li> <li>Makes forgotten remediation tasks visible.</li> <li>Helps identify services that may be affected before they fail.</li> <li>Preserves organizational knowledge.</li> <li>Goes beyond simple keyword-based search by connecting information across incidents.</li> </ul> <h2> Example </h2> <p>Suppose two previous incidents were caused by the same IAM configuration problem.</p> <p>When a similar alert appears, Faultline can connect the new alert with those incidents and show the previous solution.</p> <p>It can also identify other services that currently have the same problematic configuration.</p> <p>This gives the engineer a broader view of the problem instead of only showing the current error.</p> <h2> Memory ON vs Memory OFF </h2> <p>We also created a simple demonstration to show the importance of memory.</p> <p>With memory enabled, Faultline can retrieve:</p> <ul> <li>Previous incidents</li> <li>Previous runbooks</li> <li>Unfinished remediation tasks</li> <li>Related services</li> </ul> <p>With memory disabled, the same AI does not have access to those historical connections.</p> <p>This demonstrates that the main value comes from giving the AI persistent incident memory.</p> <h2> Evaluation </h2> <p>Our demonstration contains 19 synthetic incidents.</p> <p>We created a manually written answer key and tested whether Faultline could identify related incidents.</p> <p>It correctly identified 5 out of 6 tested relationships, giving an 83% result.</p> <p>We also show the case that was missed instead of hiding it.</p> <h2> Why This Is Different From Search </h2> <p>A normal search system can find documents containing similar words.</p> <p>Faultline is designed to connect information across multiple incidents and services.</p> <p>For example, two incidents may describe different symptoms but have the same underlying configuration problem.</p> <p>The goal is not only to find similar documents, but to connect the information and provide useful incident context.</p> <h2> Limitations </h2> <p>The current demonstration uses prepared data.</p> <p>Faultline does not yet directly check live Terraform or Kubernetes infrastructure.</p> <p>The current system reads a prepared file describing service configurations.</p> <p>Connecting Faultline to live infrastructure is an important next step toward a production-ready system.</p> <h2> Outcome </h2> <p>Faultline demonstrates how AI memory can help engineering teams preserve knowledge from previous incidents and use that knowledge when new problems occur.</p> <p>The project achieved an 83% result in the demonstrated incident-matching evaluation and showed a clear difference between memory-enabled and memory-disabled responses.</p> <h2> Future Scope </h2> <p>Future improvements could include:</p> <ul> <li>Connecting to live infrastructure.</li> <li>Automatically detecting configuration changes.</li> <li>Tracking remediation tasks until completion.</li> <li>Integrating with incident-management systems.</li> <li>Continuously updating service exposure information.</li> <li>Expanding the incident memory with real production data.</li> </ul> <h2> Conclusion </h2> <p>Every incident contains information that can help prevent future incidents.</p> <p>The challenge is remembering and connecting those lessons.</p> <p>Faultline is an attempt to give software incidents a memory — helping engineers connect new alerts with previous incidents, previous fixes, exposed services, and unfinished remediation.</p> <h1> ai #agents #devops#opensource </h1> <p><a
