MTBF (Mean Time Between Failures)
MTBF (Mean Time Between Failures) is the average time a service runs correctly between one failure and the next.
MTBF measures how often failures happen: a higher MTBF means longer stretches of healthy operation. It is the frequency counterpart to MTTR, which measures how quickly you recover.
Tracking both over time shows whether reliability work is paying off — are outages getting rarer (MTBF up) and shorter (MTTR down)?
