In v3, look for yellow or red text in the debug output. But that's only in "radiusd -X".
For radmin / raddebut, look for WARNING or ERROR.

Look for keywords. If you want to know what's going on with SQL.... look for "sql", and ignore everything else.
The information is printed because it's *needed* by someone. It's up to you to filter through it for the information you want.

Yes. Having debugging output is infinitely better than having no debug output. :(
