For which event type does Instana create an alert because end users are impacted?

Based on IBM Instana documentation review, Incidents are the event type that triggers alerts when end users are impacted. The official IBM documentation states: "An incident helps you to understand situations impacting your edge services and critical infrastructure... Incidents are created as soon as Instana detects either a key performance indication (KPI) is breached on an edge service, or a critical infrastructure issue." However, the documentation also clarifies: "An issue is an event that is triggered if something out of the ordinary happens... An issue by itself does not trigger an alert, Instana simply notes that it happened. Should the service to where this system is connected behave badly, this issue is part of the incident." Critical issues can trigger alerts and may impact end users, but Incidents are specifically designed to represent situations where end-user-facing services (edge services) are impacted. The answer is B. Incident as the primary event type for end-user impact alerts.
