know "who viewed this document" in CSOM
In CSOM there is no way to know "who viewed this file". In the sharepoint UI (web browser) there is a way (but it's not working fine with some file types like .jpg). I understand this information is taken from the analytics but this level of details is not available through CSOM. It would be great if you can provide this informnation in CSOM and if file types like jpg and other related excluded types also provide this information.
