I just look at this query guven by mcst from this link http://support.microsoft.com/kb/918483, but I have difficulties to understand how to interpret data from this dmv results.
I ran this one server and it return me many results with

RESOURCE_MEMPHYSICAL_LOW
RESOURCE_MEM_STEADY_HIGH




SELECT CONVERT (varchar(30), GETDATE(), 121) as runtime,
DATEADD (ms, -1 * (sys.ms_ticks - a.[Record Time]), GETDATE()) AS Notification_time,  
 a.* , sys.ms_ticks AS [Current Time]
 FROM 
 (SELECT x.value('(//Record/ResourceMonitor/Notification)[1]', 'varchar(30)') AS [Notification_type], 
 x.value('(//Record/MemoryRecord/MemoryUtilization)[1]', 'bigint') AS [MemoryUtilization %], 
 x.value('(//Record/MemoryRecord/TotalPhysicalMemory)[1]', 'bigint') AS [TotalPhysicalMemory_KB], 
 x.value('(//Record/MemoryRecord/AvailablePhysicalMemory)[1]', 'bigint') AS [AvailablePhysicalMemory_KB], 
 x.value('(//Record/MemoryRecord/TotalPageFile)[1]', 'bigint') AS [TotalPageFile_KB], 
 x.value('(//Record/MemoryRecord/AvailablePageFile)[1]', 'bigint') AS [AvailablePageFile_KB], 
 x.value('(//Record/MemoryRecord/TotalVirtualAddressSpace)[1]', 'bigint') AS [TotalVirtualAddressSpace_KB], 
 x.value('(//Record/MemoryRecord/AvailableVirtualAddressSpace)[1]', 'bigint') AS [AvailableVirtualAddressSpace_KB], 
 x.value('(//Record/MemoryNode/@id)[1]', 'bigint') AS [Node Id], 
 x.value('(//Record/MemoryNode/ReservedMemory)[1]', 'bigint') AS [SQL_ReservedMemory_KB], 
 x.value('(//Record/MemoryNode/CommittedMemory)[1]', 'bigint') AS [SQL_CommittedMemory_KB], 
 x.value('(//Record/@id)[1]', 'bigint') AS [Record Id], 
 x.value('(//Record/@type)[1]', 'varchar(30)') AS [Type], 
 x.value('(//Record/ResourceMonitor/Indicators)[1]', 'bigint') AS [Indicators], 
 x.value('(//Record/@time)[1]', 'bigint') AS [Record Time]
 FROM (SELECT CAST (record as xml) FROM sys.dm_os_ring_buffers 
 WHERE ring_buffer_type = 'RING_BUFFER_RESOURCE_MONITOR') AS R(x)) a 
CROSS JOIN sys.dm_os_sys_info sys
ORDER BY a.[Record Time] ASC
