Specify a set of logger names and the corresponding log levels that this log recorder will collect. For example, if you specify `hudson.model.Hudson` and `info`, any logs recorded for `hudson.model.Hudson` or its descendants with the log level info or above will show up in this log recorder, unless a more specific logger with higher log level is also specific.

If you have multiple entries, a log entry will the most specific one will be collected.
