What is a true statement regarding log nodes?

Log nodes in Mendix serve an essential role in capturing and managing log messages throughout the application. A true statement regarding log nodes is that they are dynamically registered on application startup. This means that when the application is launched, it initializes the log nodes specified in the application model, allowing them to begin capturing logs from that point onward. This dynamic registration facilitates flexible logging based on the configurations set in the application, enabling developers to set different logging levels and behaviors without needing to pre-define every detail at design time.

The other options do not hold true within the context of log nodes. While the idea of pre-defined log nodes may seem plausible, log nodes are essentially configurations that become active upon application startup rather than being fixed entities defined solely during the design phase. Furthermore, log nodes can be modified after creation through changes in the application code or model, allowing for an adaptable logging strategy. Lastly, log nodes are not specific to user sessions; they operate at the application level, capturing system-wide logs rather than being tied to individual sessions or user activities.
