depends on what you mean by "stored procedure fail logs"
do you mean when an error occurs in a stored procedure? doesn't exist unless you've created a server side trace capturing errors. there is no way to find info prior to the creation of that trace, if you were to create it now.
if you mean which procedure do not compile all of the sudden, i can point you to a script that finds invalid objects, where a table or column might have gotton dropped or changed, and the proces/views/etc were not updated to match.
