Class SSAMetricPoint

java.lang.Object
jline.streaming.SSAMetricPoint
All Implemented Interfaces:
Serializable
public class SSAMetricPoint extends Object implements Serializable
Internal representation of a metric point from SSA simulation. Used to collect metrics before sending to OTLP receiver. Metric names are aligned with line-est MetricType enum: - queue_length -> QLen - utilization -> Util - throughput -> Tput - response_time -> RespT - arrival_rate -> ArvR
