Rock provides a simple, easy to use logging tool. Most of the time you won't need this but having logs can be helpful when troubleshooting or researching. The Rock Log is similar to the Exception List, except you can track more than just errors. Logs are turned off by default, and typically should only be turned on if there is a specific need. To enable Rock logging, simply select the Verbosity Level and the domain or domains you want to output. You have the following choices for the Verbosity Level: Off: No logging should be performed.Fatal: Very severe error events that will presumably lead Rock to abort.Error: Error events that might still allow Rock to continue running.Warning: Potentially harmful situations.Info: Defines the default set of levels recognized by the system.Debug: Fine-grained informational events that are most useful for debugging Rock.All: Log everything.
