The class Unisys.Common.Shared.Logging provides methods for writing messages to the Windows Application Log (as viewed with Windows Event Viewer) and to the ePortal trace file. Calls to Logging methods require a LogLevel parameter, which is used to filter what is logged. Only calls with a parameter greater than or equal to the log level will be logged.
The LogLevel parameter is specified using the enumerated type Unisys.Common.Shared.Logging.LogLevel. The values for Unisys.Common.Shared.Logging.LogLevel include:
Error – This message is an error message; written to the Windows Application Log and ePortal trace file.
Warning - This message is a warning message; written to the Windows Application Log and ePortal trace file.
Information - This message is an informational message; written to the ePortal trace file.
Verbose – This message is a detailed trace message; written to the ePortal trace file.
Unconditional – This message is an uncategorized message; written to the Windows Application Log and ePortal trace file regardless of the configured log level.
Debug - If the configured log level is Verbose, this message will be written to the trace file and also to the Visual Studio output window. To display the Visual Studio output window, open the View menu, then click Output.
For information on configuring the log level while testing, refer to Logging Errors and Tracing.
