Can anyone provide additional information other then what SolarWinds lists on their requirements and FAQ pages as to why this is a requirement for NTA 4.4?
Do I need some special SQL server permissions?
Yes. The NTA Flow Storage database account requires the ALTER ANY CONNECTION permission in order to schedule and optimize the daily database maintenance task. This ensures that SolarWinds minimizes the performance impact of the maintenance task, and maintains the overall performance of the database.
Using SQL Management Studio, run the following command to grant permissions:
USEmaster
GRANTALTERANY CONNECTION TO<grantee> [ AS<grantor> ]
Any insight regarding it would be greatly appreciated.
