An administrator can configure how Exago handles logging in order to change or extend functionality.
By default Exago saves a log file called ‘WebReportsLog.txt’ to the application’s Temp path (specified in ‘WebReports.xml’). The logger maintains a lock on the file for the lifespan of the application. The log file cannot be edited or deleted without restarting the application or releasing the lock.
There are three configurable verbosity levels for the logger. By default, Exago runs at the Info level.
Use the following administrative setting to set the log level or disable logging:
( Other Settings ) Write Log File
Start time, userId, companyId, full report name, filter summary.
End time, runtime, userId, companyId, full report name.
The logger can load its configuration from a file and continually watch the file for changes. A config file can be used to lock or unlock the log file, change the log file name and path, as well as customize and extend logging capability.
Note: A custom log configuration file will override the application's configuration settings.
To use a custom log configuration, create a file called ‘log4net.config’ in the Config directory of the Exago application. The following shows a sample config file:
<?xml version="1.0" encoding="UTF-8"?> <log4net> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\Exago\Temp\WebReportsLog.txt" /> <encoding value="utf-8" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <lockingModel type="log4net.Appender.FileAppender+ExclusiveLock" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %-5level [%property{SessionId}] %message%newline" /> </layout> </appender> <!-- Setup the root category, add the appenders and set the default level --> <root> <level value="INFO" /> <appender-ref ref="RollingFileAppender" /> </root> </log4net>
For more information and extensibility, see: Apache log4net. See the following examples for some simple modifications:
<file value="Path\To\Log.txt" />
Specifies the directory and filename for the log file.
<level value="INFO" />
Specifies the Exago logging level: ERROR, INFO, or DEBUG.
<lockingModel type="log4net.Appender.FileAppender+ExclusiveLock" />
Configures the locking model in use for the log file. To temporarily disable the write lock, you can use: log4net.Appender.FileAppender+MinimalLock
NOTE. This will result in a performance reduction until it is reset.
