Overview
This article explains the different verbosity levels available in BlackBox logging for MagicLogic and how they impact the detail captured in the log output. Verbosity settings control how much information is written to the log files during optimization. Adjusting this setting is helpful for troubleshooting, performance monitoring, or minimizing log file size during normal operation.
Requirements
- BlackBox version 5.
- BlackBox version 4.
Product Information
The Verbosity Level setting in BlackBox controls the amount of detail written to the log files during the optimization process.
Key: Log Message Severity Filters (I, W, E, F)
I – Informational
Lowest severity. Reports on routine system activity such as startup, garbage collection, etc.
Use to monitor normal BlackBox operations.W – Warning
Indicates notable but non-critical issues, such as system reloads or data warnings (e.g., zero quantity products).
Useful for catching potential data quality issues without processing being stopped.E – Error
Highlights serious problems that may impact optimization results, such as missing or malformed data.
Recommended when troubleshooting incorrect load outcomes.F – Fatal
Highest severity. Flags critical system issues like licensing violations or hardware failure.
Very rare—requires immediate attention and system shutdown.
Each level affects logging as follows:
0 – Silent
No standard log output. Only FATAL errors are logged.
Use for production environments where only critical failures matter.1 – Errors Only
Logs ERROR and FATAL messages.
Useful for identifying major problems without log noise.2–8 – Standard Logging Range
Logs WARNING, ERROR, FATAL, and some additional internal or special events.
Most commonly used range for general troubleshooting or monitoring.9 – Diagnostic Trace
Maximum verbosity. Logs all internal processes, calculations, and diagnostic details.
Best used for deep debugging or when directed by MagicLogic Support. May generate large log files.
