How to architect your context lake for self-healing incidents
Blog post from Port
Self-healing incident response depends on a structured “context lake,” described as a living graph that connects services with ownership, dependencies, deployments, pull requests, incident history, runbooks, standards, and operational metrics rather than merely storing raw telemetry. This context allows agents to identify affected services, rank likely causes, recommend evidence-backed actions, and operate within predefined approval gates through a Detect, Diagnose, Recommend, Act, and Learn workflow, while humans remain accountable for outcomes. The article contrasts this approach with unstructured investigations across multiple tools, arguing that disconnected logs and dashboards can lead agents to pursue weak hypotheses and lengthen diagnosis times. It recommends beginning with a low-risk service, integrating existing code, deployment, monitoring, and incident systems, linking change and incident histories, and automating only a bounded, pre-approved recovery path such as routing, restart, or rollback. Examples involving sports media company Sportradar and payments firm dLocal illustrate how Port’s catalog-based platform is presented as a source of operational context and governance, with proposed success measures including time to first assessment, mean time to resolution, false positives, escalation rates, and acceptance of agent recommendations.
