XF 1.5 Error reporting after vB->xF migration?

[Peace]

Hey everyone! Wanted to see if you know of any specific tools that can help to identify error pages in real time? Basically, I'm looking for a way to monitor 404s (and others) once we migrate to xenForo, to see if I missed any important redirects.

Do you know of any scripts or tools that can help me see these errors in real time, and identify any important trends so I can write the missing redirects on the fly? I think I've got almost everything covered, but still paranoid and don't want to lose potential visitors!

Thanks

Do you have Google Webmaster Tools set up with your site? That's probably the easiest thing to use to identify 404s.
