I can see proper values for Usage reports at site collections and sites level. SharePoint also provides a way to get Usage reports in List items level. I always get zero values in Usage reports for all the list items in my farm. I looked at the crawl history, and found List item or document is crawled, still it is showing zero values for those list items. Does anyone have any idea why this is not working for List item or document? Please anyone help me to get it resolved.
