I´ve been searching in thwack, but nothing has appeared.
Just want to know which features are necessary to choose in the "Feature Selection" step when installing SQL Server 2017 for SAM,
Thank you
See SolarWinds Orion Platform requirements
You do not need SQL SRS for SolarWinds, but some people use it if you're good with BI.
Other components are generally not required. Just the very basics of a SQL install following the guidelines above.
Following the above guide and selecting the DB engine should be enough, but I'd get guidance from your DBA to review this - SQL Server Configuration Best Practices
Thank you!
