RecallOps is an engineering incident response application that introduces persistent memory to enhance investigation and learning. The dashboard provides a centralized view of active incidents and allows engineers to investigate using memory, review analysis, and record outcomes. At its core, RecallOps utilizes Hindsight, a central memory layer, to retrieve relevant past experiences when a new incident occurs.
Two essential operations in this implementation are Recall and Retain. Recall triggers a search of Hindsight's persistent memory using the current incident's symptoms and context. This enables the system to present relevant past incidents, patterns, recommended fixes, and historical lessons to support the engineer's investigation.
When an engineer clicks "Investigate" with Recall, the system searches Hindsight for memories that match the current incident, providing a valuable starting point rather than forcing the engineer to start the investigation anew. The integration of RecallOps with Hindsight allows engineers to benefit from previous experiences, helping them understand possible root causes and solutions, apply fixes, and record outcomes.
This creates a continuous learning loop, where each investigation contributes to future investigations by adding to the team's engineering knowledge. RecallOps employs Python Flask, HTML, CSS, JavaScript, and SQLite for its technical implementation. The front-end presents the incident command-center interface, while Flask handles the application and API routes.
The integration with Hindsight occurs through a service layer, allowing seamless communication between the main application and Hindsight's memory operations. Engineers can record whether the recommended solution worked or failed, providing valuable information for future investigations. By connecting previous experiences with current incidents, RecallOps transforms incident history into reusable engineering experience, ultimately making future investigations more informed and efficient.
