Log Reader - Configure Custom Patterns

If I wanted this log entry to be a trigger, what would I enter into the Log Reader Binding, and would I put that in the Event box when I set up a trigger in a rule, or in the Custom Patterns box in the binding Thing - both?

[INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'Test_Switch' changed from OFF to ON

I see that in teh binding WARN+ and ERROR+ are shown in teh warn and error battern boxes so I tried INFO+ there and then “openhab.event.ItemStateChangedEvent” in teh trigger box but I’m not getting anything.
