How do I get a TestNG report to show console output?

How do I get my TestNG report to show a link to the console output from the report? I've seen TestNG do it before but a project I am working on right now isn't showing any of the output and I can't find any information anywhere that says how to turn it on. I tried setting the "verbose" option in the testng.xml suite tag but that didn't have any effect at all.
