What is MTTD and MTTR?

Mean Time To Detect (MTTD) and Mean Time To Restore (MTTR) are metrics used to describe how long it takes to discover a problem and how long it takes you to restore service relative to the start of the outage. The shorter the MTTR, the less time spent in outage and the more availability your site retains.

How do you calculate MTTR?

To calculate MTTR, divide the total maintenance time by the total number of maintenance actions over a given period of time. Imagine a pump that fails three times over the span of a workday. The time spent repairing each of those breakdowns totals one hour. In that case, MTTR would be 1 hour / 3 = 20 minutes.
