# Log Sheet

After defining your metrics in the Metrics Inventory sheet, you will log the measurements in the log sheet. The log sheet has the following columns:

<table><thead><tr><th>Column</th><th>Description</th><th>Example</th><th data-type="checkbox">Required</th></tr></thead><tbody><tr><td>Metric ID</td><td>The unique identifier of the metric. This must match to the Metric ID defined in the Metric Inventory.</td><td>M-01</td><td>true</td></tr><tr><td>Value</td><td>The value of the measurement being reported. Do not format this column. Use decimal format for percentages.</td><td>0.8</td><td>true</td></tr><tr><td>Measurement Date</td><td>The date of the measurement.</td><td>08/31/2025</td><td>true</td></tr><tr><td>Notes</td><td>Any notes associated with the measurement.</td><td>We’ve seen a slight dip in coverage this month, primarily due to delays in onboarding new contractor workstations. A remediation plan is in place.</td><td>false</td></tr></tbody></table>

## Recording Measurements

Once a metric has been added to the Metric Inventory Sheet, you will need to record measurements in the Log Sheet. A measurement is a single value for a metric tied to a measurement date. Metrics may have different measurement cadences: some may be measured quarterly, others weekly or even daily.&#x20;

All measurements must be added to the log. To add a measurement, add the Metric ID the measurement is for, the measured value, the date of the measurement, and optionally add notes for added context.

Some things to keep in mind:

* The Metric ID must match the ID from the Metric Inventory Sheet.
* The value must be unformatted. Percentages should be in decimal format.
