Does AWS RDS SQL Server support Dynamic Management Views ?

Question: Does AWS RDS SQL Server support Dynamic Management Views ? I want to be able to return memory information , including total server memory and memory pressure 

Answer:  A SQL Server installation on a Windows Server supports Dynamic Management Views (DMV)  . The same applies to AWS RDS SQL Server. 

When you execute a  SELECT @@version on an AWS RDS - it's similar to the following output .:

Microsoft SQL Server 2019 (RTM-CU8) (KB4577194) - 15.0.4073.23 (X64) Sep 23 2020 16:03:08 Copyright (C) 2019 Microsoft Corporation Enterprise Edition: Core-based Licensing (64-bit) on Windows Server 2016 Datacenter 10.0 (Build 14393: ) (Hypervisor)

To execute these examples  the required permissions are : SELECT permission on object and VIEW SERVER STATE or VIEW DATABASE STATE permission

Let's look  through a few examples of system DMVs which are supported  on AWS RDS SQL Server

--find total server memory 

SELECT total_physical_memory_kb / 1024 AS MemoryMb FROM sys.dm_os_sys_memory;


--identify memory pressure 



SELECT
    EventTime,
    record.value('(/Record/ResourceMonitor/Notification)[1]', 'varchar(max)') as [Type],
    record.value('(/Record/MemoryRecord/AvailablePhysicalMemory)[1]', 'bigint') AS [Avail Phys Mem, Kb],
    record.value('(/Record/MemoryRecord/AvailableVirtualAddressSpace)[1]', 'bigint') AS [Avail VAS, Kb]
FROM (
    SELECT
        DATEADD (ss, (-1 * ((cpu_ticks / CONVERT (float, ( cpu_ticks / ms_ticks ))) - [timestamp])/1000), GETDATE()) AS EventTime,
        CONVERT (xml, record) AS record
    FROM sys.dm_os_ring_buffers
    CROSS JOIN sys.dm_os_sys_info
    WHERE ring_buffer_type = 'RING_BUFFER_RESOURCE_MONITOR') AS tab
ORDER BY EventTime DESC
