Are your maintenance teams as effective as they could be? If you’re calculating time in between incidents that require repair, the initialism of choice is MTBF (mean time between failures). Examples of such devices range from self-resetting fuses, up to whole systems which have to be repaired or replaced. Mean time to repair (MTTR) is the average time required to troubleshoot and repair failed equipment and return it to normal operating conditions. The metric is used to track both the availability and reliability of a product. In other cases, there’s a lag time between the issue, when the issue is detected, and when the repairs begin.

High availability - Wikipedia The hot spare disk reduces the mean time to recovery (MTTR) for the RAID redundancy group, thus reducing the probability of a second disk failure and the resultant data loss that would occur in any singly redundant RAID (e.g., RAID-1, RAID-5, RAID-10). How to calculate mean time to recovery One of the goals of DevOps Agile IT is to reduce the Mean Time To Recovery (MTTR). With an example like light bulbs, MTTF is a metric that makes a lot of sense. This MTTR is often used in cybersecurity when measuring a team’s success in neutralizing system attacks. So, let’s say we’re assessing a 24-hour period and there were two hours of downtime in two separate incidents. You can calculate MTTR by adding up the total time spent on repairs during any given period and then dividing that time by the number of repairs. A lot of experts argue that these metrics aren’t actually that useful on their own because they don’t ask the messier questions of how incidents are resolved, what works and what doesn’t, and how, when, and why issues escalate or deescalate.
