What are MTTF (mean time to failure) and MTTR (mean time to repair)? What these metrics help us to evaluate?
Answer
- MTTF (mean time to failure) other known as uptime, can be defined as how long the system runs before if fails.
- MTTR (mean time to recover) on the other hand, is the amount of time it takes to repair a broken system.
- MTBF (mean time between failures) is the amount of time between failures of the system.
