Metrics

Below is a list of all standard Njord metric names. These have special meaning in the software, are used to calculate derived metrics, and some features are only enabled when these metrics are present.

When loading data from any data source, we will rename data to match these standard metrics. When importing data in CSV format, name the CSV columns to match the metric names below for the best experience.

Depending on the data source, you can include any number of additional metrics with custom names. They will all be shown in the software, but don't carry any special meaning.
