Which process is involved in monitoring an IT service and detecting when the performance drops below acceptable limits?

Service asset and configuration management tracks and controls IT assets and configuration items, not real-time service performance thresholds.

Event management monitors all events occurring across the IT infrastructure and services, including detection of exceptions such as performance degrading below agreed thresholds. It uses monitoring tools to capture and filter events, generating alerts or escalating to incident management when service levels are at risk.

Service catalogue management maintains information about available services and their details, not live monitoring or performance detection.

Problem management focuses on identifying root causes of incidents and preventing recurrence, not on real-time performance monitoring.
