Input Events Backlogged
Watermark Delay (indicates latency), Input Events Backlogged (backlog of unprocessed events), and Output Events (throughput) are key performance metrics for an Azure Stream Analytics job. Option C (Conversion Errors) and Option D (SU (Memory) Utilization) are not performance metrics; Conversion Errors is an error metric, and SU Utilization is a resource metric.
