A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

6-6Ensuring solution and operations excellence

A team wants its reliability target to count how many five minute periods were healthy rather than how many individual calls succeeded. Which evaluation method is that?

Windows-based evaluation of periodsCorrect · your answerCorrect. Intervals are counted, not calls.
Request-based evaluation of callsCounting calls is the other method offered here.
A distribution-cut indicator rangeThat indicator type describes a custom metric, not the counting unit.
A time-series ratio of two filtersRatio indicators build a custom metric from two filters.

Correct.

Concept

The unit a target is measured in decides what a brief severe failure costs you, since counting intervals treats a bad minute the same whether it carried ten requests or ten thousand.

Why A

Request-based evaluation measures requests meeting the criterion against total requests in a period, while windows-based evaluation measures evaluation periods meeting a goodness criterion against total periods.

Source

Request-based evaluation measures the number of requests that meet the evaluation criterion against the total number of requests in a given period. Windows-based evaluation measures the number of evaluation periods that meet a goodness criterion against the total number of evaluation periods.
