@Pocodeyo,
This question related to SHD should be posted on SHD Community page: Skyline Health Diagnostics (SHD) to get more responses.
Well, please refer this article which provides answers to FAQ about VMware SHD. In order to download SHD please go to Broadcom Support Portal and Select the vCenter version and click on 'Drivers & Tools'. Once there, you can search for Skyline and you should see the 4.0.x version. This would be the version to use as the 4.0.3 version had a number of issues which have supposedly been resolved in the latest version.
