Microsoft practices enterpriselibrary logging

Basically, the code writes to the log sink using two approaches. First, an instance of the LogEntry class is created. Its message property is populated—this appears with the entry in the log sink.

The Write method of the Logger class is used to send the LogEntry object to the log sink. The final line uses a basic text message to make an entry in the log sink event log in this case. You need to complete one final step before you can use this code in your application: You need to configure logging. The Enterprise Library uses the Enterprise Library Configuration Console, a graphical tool that allows changing and validating an application block's configuration settings XML configuration file by eliminating the difficulties that are encountered during manual settings.

It is accessible via the Enterprise Library program group installed on your machine. The console is used to create the configuration files necessary for your application to utilize one or more of the application blocks. The following steps are followed to create the files. In the Enterprise Library Configuration Console, follow these steps:. We've covered the most basic aspects of logging with the Logging and Instrumentation Application Block; the application block provides many more features that may be utilized.

You may choose to log events to a flat file, a SQL Server database, or expand it by developing your own custom log sink. In addition, the instrumentation features may be utilized. These are not enabled with the default Enterprise Library installation. Answered by:. Archived Forums. Visual C. Sign in to vote. Hi All, Here is my code, the program exits once the logger.

Split ',' ; cID. Write line it automatically exits, not executing the return statement. Can anyone tell me why and how can I change my code to execute the return statemnt also? Perhaps the best way to get to grips with the Logging and Instrumentation Application Block is to try it. The download for this article contains the code for a sample Windows Forms application LoggingBlockInvestigator.

You may need to delete and re-add its reference to the various Microsoft. EnterpriseLibrary assemblies. The LoggingBlockInvestigator. This code shows two techniques for writing Log Entries with the Default Category. The first technique explicitly creates a LogEntry object and initializes it with a message. The second, more compact technique creates the LogEntry implicitly. If you build and run the LoggingBlockInvestigator. If you look at the details, you will see a list of each of the Log Entries' properties.

By default, all Log Entries are marked with the Default Category. Under the System Log, you will find an entry with a source of "Logging Investigator". Looking at the details will show that the Category is set to "My Category". If you open that file, you will find it contains the same Log Entry except formatted differently, as the second Destination is set to use a different Formatter.

The code above uses a LogEntry. When a LogEntry is written, it can be given a priority. If not specified, this defaults to the currently configured Minimum Priority. This code actually tries to write two Log Entries. However, if you look in the Windows Event Log, you will find the first one has been filtered out.

This is because the configuration files for the LoggingBlockInvestigator. As well as using the provided Log Sinks, you can create your own. The class is derived from Microsoft. As well as writing a Log Event, the example shows how to read the configuration information for the Log Sink. As of 9 February , this is incorrect.

You can add additional information to a LogEntry and have it persisted to a Log Sink. The example shows how to add information directly and how to use one of the IExtraInformationProvider objects:.
