How much of a performance hit would running SQL Profiler on a Production Database be? What if you are only capturing events that happen infrequently (like once a second)?

It does consume quite a bit of CPU. You should run server side traces instead of profiler on production..

If you don't want to run a server-side trace, then make sure to run SQL Profiler on a client machine (not on the actual db server) and have it save the data to a file (not a table). Here's my blog on Profiler tips: http://weblogs.sqlteam.com/tarad/archive/2008/08/06/SQL-Profiler-best-practices.aspx
