Class LoggerNodeParam

java.lang.Object

jline.lang.NodeParam

jline.lang.nodeparam.LoggerNodeParam

All Implemented Interfaces:

Serializable

public class LoggerNodeParam
extends NodeParam

Parameter container for logger nodes in queueing networks.

This class configures logger nodes that record job passage events, service times, and other performance metrics to files. Logger nodes are essential for trace generation, performance monitoring, and validation of analytical results against simulation.

Logging capabilities include:

• Job event logging with timestamps and job identifiers
• Service time measurements for same-class and cross-class interactions
• Configurable output formats and file destinations
• Real-time performance monitoring
• Trace generation for replay and analysis

Since:

1.0
