Impact Analysis maps every incident's blast radius across your service topology in real time. See which downstream services are affected, how many users are impacted, and what the estimated revenue cost is, the moment an incident is detected, not after a 30-minute war room call.
When an incident fires on a service, Nova traverses your live service dependency graph to identify every downstream service that could be affected. The blast radius renders as a visual overlay on your service map: the origin service in red, directly impacted dependencies in orange, and potentially affected services in yellow. Incident commanders see the full scope of impact in a single glance instead of manually checking service by service.
Nova correlates affected services with business metrics to estimate the financial impact of each incident. If the checkout service is down, Nova multiplies average transaction value by current traffic rate to project revenue loss per minute. If the authentication service is degraded, Nova counts active sessions to report affected users. These numbers appear on the incident card within seconds, giving executives and incident commanders the business context they need to make priority decisions.
Impact Analysis relies on an accurate service dependency graph, and Nova builds it automatically from your distributed traces, network flows, and API call patterns. No manual topology files to maintain. When a new service deploys or a dependency changes, the graph updates within minutes. You can also annotate services with business criticality tiers, revenue attribution, and team ownership to enrich impact calculations.
Map blast radius, count affected users, and estimate revenue impact the moment an incident is detected.
