Welcome to Skyline Communities !!!
When you refer to health report are you referring to Operational Summary Reports(OSR)?
If so, as of now, the ability to view the OSR Library page and download Operational Summary Reports is available to Premier Support customers only.
However if you are looking to have a report on the present findings we can export them.
The findings and recommendations page contains all findings discovered by Skyline, findings muted by a user, and upgrade recommendations.
Click the Export button to export all affected objects in CSV format. The CSV file will contain the following information for the Affected Objects: Source Name, Object Name, Object Type, Solution Tags, Summary, First Observed.
