Gents,

Solar Winds requires a database user that can access system tables to query database sta s cs. (This is a “master key”

Solar Winds will have as you now.)

I was talking with Demetrios over lunch.

I look forward to reviewing our SQL-Server code for our eligibility process, learn more and help where I can, especially

with our slowly changing dimensions (SCD Type 1 and 2) and Change Data Capture (CDC).

Kind Regards,

Albert

More technical notes…

 Define what users can access and do in the SolarWinds Pla orm

o SQL permission role requirements on the SolarWinds Orion Pla orm

o Portal Security (solarwinds.com)

SQL Server has a system view sys.dm_os_performance_counters which I will put $ on Solar Winds is querying (think

Oracle Statspack)

sys.dm_os_performance_counters" is equivalent to "being a Server admin or an Azure Ac ve Directory admin"
