Which ITIL practice is closely related to Event Management regarding performance metrics?

Service Level Management is the ITIL practice most closely related to Event Management when it comes to performance metrics. This is because Service Level Management is responsible for negotiating, defining, and managing service level agreements (SLAs) that specify the expected performance and availability of IT services. Event Management supports this by tracking and logging events that may impact those services, providing valuable data that can be analyzed to ensure that SLAs are being met.

Events captured during the Event Management process can indicate performance issues or anomalies that might require further investigation. By analyzing these events, Service Level Management can assess whether the service is performing in line with the agreed-upon metrics in the SLAs, enabling proactive management of service quality and customer expectations.

In contrast, while the other practices like Incident Management, Change Management, and Problem Management are important components of service management, they do not directly focus on the measurement and management of service performance against defined metrics in the way Service Level Management does related to Event Management.
