Transaction monitoring involves analyzing customer activity to detect unusual or suspicious patterns. A key component of managing this process is measuring its effectiveness and efficiency through Key Performance Indicators (KPIs) and Key Risk Indicators (KRIs). The "number of alerts raised to a case analyzed by a front line unit" is a critical metric. It helps assess the quality of alerts generated by the system (i.e., the false positive rate) and the initial triage process, which are core parts of the monitoring function.

A. This is a performance metric (KPI) for a specific team's efficiency, which is an outcome of monitoring, but not part of the monitoring activity itself.

B. A backlog of customer data is an operational problem or a data management issue, not a metric or activity included within the monitoring process.

D. Alerts from a lookback are part of a specific, retrospective project to review historical activity, not part of routine, ongoing transaction monitoring.
