The Message Source pane allows you to configure the WorkView features for which you want to log messages. This will allow you to customize the messages logged based on the sources you have configured in your solution or those sources that you are troubleshooting specifically. Each Source has a Level drop-down list that allows you to specify the amount of logging you want to see from 0 to 4. A 0 setting will not log any information for the corresponding source. Logging increases as the Level number increases. It is recommended to start at Level 1 and increase the Level number if you require more information.
