I believe you are calculating metrics using the Clickstream data stored on AWS.
For PDF Downloads, the call fired is a custom link call and those can be filtered based on page_event. Hence apply filter for "post_page_event = 101". For Video Plays, you can try "post_page_event = 76".
Kaushal - Thanks for your response earlier. It looks like pdf downloads is working at my end. However, I am not able to isolate video plays using the condition you stated. Is it possible there is another filter to video play? Let me know. I have already tried all possible filters under post_page_event. But that does not give me any result.
