Which of the following would be implemented in a software management tool to define boundaries that generate notifications?

Audit logs record security-relevant events and user actions, but they do not define the boundaries for generating notifications based on performance or operational metrics.

Baselines represent a normal operating range or expected behavior for a system, providing a reference point, but they are not the direct mechanism for triggering notifications when boundaries are breached.

Thresholds are predefined limits for performance metrics or other measurable data points in a monitoring system. When a monitored value crosses a defined threshold, such as CPU utilization exceeding 90%, the software management tool generates an alert or notification to indicate a potential issue.

Events are occurrences in a system that might be *generated* when a threshold is crossed, but the term 'events' itself does not define the boundaries that cause notifications.
