SmartConnector download and document

Hi All

    I know sentinel could integrate with arcsight SmartConnector.

But Now I check sentinel marketplace webpage...

In Sentinel section...There is no SmartConnect download.

In Arcsight, there is SmartConnector section...but it only provide "update" , no SmartConnector download and document.

In SLDPortal , I check the latest sentinel 8.6 download webpage....there still no smartconnector download page / Document.

the SmartConnect seem could support let some event log convert to CEF 

I want to study Smart Connector ...

where is official download link and document to learn how to use smartconnecor receive log (for example: ESXi log)

Thanks!
