Sensor missing-data coverage calculator

Calculate schedule coverage and missing scheduled timestamps with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use schedule coverage and missing scheduled timestamps to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Schedule coverage (%)

Each expected timestamp matched within tolerance. Longest consecutive missing run multiplied by uniform scheduled interval.

Missing scheduled timestamps

Each expected timestamp matched within tolerance. Longest consecutive missing run multiplied by uniform scheduled interval.

Longest consecutive missing slots

Each expected timestamp matched within tolerance. Longest consecutive missing run multiplied by uniform scheduled interval.

Longest outage represented by missing slots (minutes)

Each expected timestamp matched within tolerance. Longest consecutive missing run multiplied by uniform scheduled interval.

Symbols and units

Expected schedule timestamps (minutes)
b
Received timestamps (minutes)
c
Timestamp matching tolerance (minutes)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Uniform expected schedule, timestamp matching with entered tolerance; outage duration counts missing slots, not time between successful records. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Uniform expected schedule, timestamp matching with entered tolerance; outage duration counts missing slots, not time between successful records.
