Logging Levels

The following are the different types of messages that may be included in a log for Loftware Enterprise SP:

  • Fatal error messages: These messages indicate situations in which the application must shut down or is unusable.
  • Error messages: These messages indicate that the application is in an unexpected and possibly compromised state. A user may have performed an action that compromised the application.
  • Warning messages: These messages indicate that something unintended and notable occurred in the application, or may indicate an important application state change. The application may have acted in a way that is a cause for concern, but has not impacted the stability of the application. A user may have made a mistake, but has not compromised the application.
  • Informational messages: These messages indicate that something notable occurred, such as the printing of a label and the startup or shutdown of Loftware Enterprise SP. These messages may provide helpful information if a problem is occurring, but their existence does not indicate a problem.
  • Debugging messages: These messages provide debugging information that may help a technical support engineer or a developer at Loftware diagnose a problem with the application.
