What distinguishes a Metric-based Indicator?

A Metric-based Indicator is distinguished by its source, which is specifically a metric table or view. This characteristic is fundamental because metric tables or views contain predefined calculations, aggregations, or metrics that are essential for analytical purposes. These sources provide the data that the indicator analyzes and presents, enabling users to derive insights based on quantifiable measures.

In contrast, other options do not accurately define a Metric-based Indicator. For instance, requiring user input is not a defining feature of such indicators, as they are typically designed to automate the analysis and presentation of metrics without necessitating manual data entry. Furthermore, being based solely on historical data does not apply, as indicators may also represent real-time or current data, depending on the context and configuration. The ability to exist without a metric table is also not applicable, as the essence of a Metric-based Indicator lies in its connection to a metric source, which is crucial for ensuring that the data being analyzed is relevant and structured for performance evaluation.
