These are available in the ResourceMonitor/Notification property within the XML. They are an absolute indicator of a low memory condition on your machine, so if you get the alert, you were low on either external/OS/physical memory, or internal/SQL Server/virtual memory.[/quote]If you filter for those two events, when either one occurs, you have low memory of some type. To set up the alert, you'll need to connect your PowerShell script to email you in the event you get those results.Thu, 27 Sep 2012 04:30:10 GMTGrant Fritcheyhttp://www.sqlservercentral.com/Forums/Topic1364365-1550-1.aspxHello Grant,I ran the code below from your simple talk article. But do not see how an alert is generated. Could you help me.WITH RingBuffer AS (SELECT CAST(dorb.record AS XML) AS xRecord, dorb.TIMESTAMP FROM sys.dm_os_ring_buffers AS dorb WHERE dorb.ring_buffer_type = 'RING_BUFFER_RESOURCE_MONITOR' ) SELECT xr.value('(ResourceMonitor/Notification)[1]', 'varchar(75)') AS RmNotification, xr.value('(ResourceMonitor/IndicatorsProcess)[1]', 'tinyint') AS IndicatorsProcess, xr.value('(ResourceMonitor/IndicatorsSystem)[1]', 'tinyint') AS IndicatorsSystem, DATEADD(ss, (-1 * ((dosi.cpu_ticks / CONVERT (FLOAT, (dosi.cpu_ticks / dosi.ms_ticks))) - rb.TIMESTAMP) / 1000), GETDATE()) AS RmDateTime, xr.value('(MemoryNode/TargetMemory)[1]', 'bigint') AS TargetMemory, xr.value('(MemoryNode/ReserveMemory)[1]', 'bigint') AS ReserveMemory, xr.value('(MemoryNode/CommittedMemory)[1]', 'bigint') AS CommitedMemory, xr.value('(MemoryNode/SharedMemory)[1]', 'bigint') AS SharedMemory, xr.value('(MemoryNode/PagesMemory)[1]', 'bigint') AS PagesMemory, xr.value('(MemoryRecord/MemoryUtilization)[1]', 'bigint') AS MemoryUtilization, xr.value('(MemoryRecord/TotalPhysicalMemory)[1]', 'bigint') AS TotalPhysicalMemory, xr.value('(MemoryRecord/AvailablePhysicalMemory)[1]', 'bigint') AS AvailablePhysicalMemory, xr.value('(MemoryRecord/TotalPageFile)[1]', 'bigint') AS TotalPageFile, xr.value('(MemoryRecord/AvailablePageFile)[1]', 'bigint') AS AvailablePageFile, xr.value('(MemoryRecord/TotalVirtualAddressSpace)[1]', 'bigint') AS TotalVirtualAddressSpace, xr.value('(MemoryRecord/AvailableVirtualAddressSpace)[1]', 'bigint') AS AvailableVirtualAddressSpace, xr.value('(MemoryRecord/AvailableExtendedVirtualAddressSpace)[1]', 'bigint') AS AvailableExtendedVirtualAddressSpace FROM RingBuffer AS rb CROSS APPLY rb.xRecord.nodes('Record') record (xr) CROSS JOIN sys.dm_os_sys_info AS dosi ORDER BY RmDateTime DESC; thanksBrianWed, 26 Sep 2012 14:39:18 GMTbmanning 59285http://www.sqlservercentral.com/Forums/Topic1364365-1550-1.aspxYou can check the ring buffers for one of three different error messages, Out of Memory messages, Low Physical memory or Low Virtual memory. You can also use the DBCC MEMORY_STATUS to compare target committed to current committed. I go over all these with example scripts in [url=http://www.simple-talk.com/sql/database-administration/why-is-that-sql-server-instance-under-stress/]this Simple-Talk article[/url]. Just run these scripts from PowerShell if that's what you need.Wed, 26 Sep 2012 03:49:57 GMTGrant Fritcheyhttp://www.sqlservercentral.com/Forums/Topic1364365-1550-1.aspxI recommend using Page Faults (not a SQL Server specific indicator) to indicate when the memory is falling to the page/swap file as your indicator. There's usually a little traffic there even under no pressure so you'll want to check your system for tolerance levels while it's running 'cleanly'.Tue, 25 Sep 2012 17:27:18 GMTEvil Kraig Fhttp://www.sqlservercentral.com/Forums/Topic1364365-1550-1.aspxI Need a Memory Utilization alert SQL Server 2008 r2. I am not sure which alert in sql server will statisfy for Memory Utilization. I would be interested in a powershell scipt that gives an alert if memory resources are maxed out.Tue, 25 Sep 2012 17:24:38 GMTbmanning 59285
