Final answer:
The Mean Time to Recovery (MTTR) is the metric used to describe how quickly a service is restored after a failure, being crucial for service management and IT operations to minimize downtime.
Step-by-step explanation:
The metric that measures how quickly a service is restored after a failure is known as the Mean Time to Recovery (MTTR). MTTR is a critical performance indicator in the field of service management and IT operations. It specifically refers to the average time required to repair a failed component or return a service to functionality. This includes the time to diagnose the problem, implement a fix, and confirm that the service is operational again.
Organizations strive to minimize MTTR in order to reduce downtime and maintain high levels of service availability and reliability.The metric that measures how quickly a service is restored after a failure is called Mean Time to Recovery (MTTR). MTTR is the average time it takes for a service or system to recover from a failure and resume normal operation. It is an important measure to assess the reliability and performance of a service or system.
