Had a request to see how often a pdf was being used within a document library so i setup a test library in one of my team sites and was able to enable auditing on the library, after some open attempts on the PDFs i placed in it...i ran the site collection audit report to see the numbers and it generated properly.
WHen i tried to recreate the scenario in another site however, i wasn't able to see pdf files on the report...the auditing would show me .doc files and .xls files but not show me any stats on the .pdf files. Is there something i have to configure in the library so that PDF files are visable on the reports...something that might have been enabled in my test site that wasn't in this other site?
really scratching my head on this one....
