How to get log from user

I have a bit of trouble getting a relevant log from a user. I asked him to invoke Console.app, type the keyword of my log messages in the search box, then run my app, then send me all the messages. Unfortunately, no message appear in Console.app. He has sent me a screenshot of Console.app, too. T
