Which of the following metrics used to measure the effectiveness of a run book represents the average time to recover a system from a hardware failure?
Mean time to recover (MTTR) is average time to recover a system from a hardware failure. Should a component or an entire system fail, it is important to know how long it would take to repair it, or how long it would be before a replacement could be up and running.
The mean time between failures (MTBF) is the estimated amount of time that a piece of equipment should remain operational before failure. The MTBF is usually supplied by the hardware vendor or third party. MTBF can also be referred to as mean time to failure (MTTF).
Mean time to failure (MTTF) is the average time until the first failure occurs in a piece of equipment.
Failure in time (FIT) is another way of reporting MTBF. FIT reports the number of expected failures per one billion hours of operation for a device.
