The reason I'd start here is because its very quick to check on the VMs from a high level where as memory investigation within the VM itself and SQL Server will require more time.Confirm you're VM isn't having pressure from it's neighbors and then drill down into it.Here are the esxtop commands. He or she would just have to look at "MEMCTL" (MB) to tell if there is ballooning taking place.http://communities.vmware.com/docs/DOC-9279Wed, 26 Sep 2012 19:00:47 GMTAmarettoSlimhttp://www.sqlservercentral.com/Forums/Topic1362292-1550-1.aspxConsult with your vm admin, if memory ballooning becomes a problem you may have to uninstall the balloon driver from the vmware tools but simply having the admin reserve resources should be sufficient.Sat, 22 Sep 2012 02:36:52 GMTPerry Whittlehttp://www.sqlservercentral.com/Forums/Topic1362292-1550-1.aspxThanks!Fri, 21 Sep 2012 06:58:40 GMTjberg-604007http://www.sqlservercentral.com/Forums/Topic1362292-1550-1.aspxIf you want to measure memory usage of Buffer pool,Select Count(*) * 8 / (1024.00) 'BufferPoolSize In MB' From sys.dm_os_buffer_descriptorsFri, 21 Sep 2012 03:06:01 GMTSQL Showhttp://www.sqlservercentral.com/Forums/Topic1362292-1550-1.aspxMeasure total server memory used by SQL Server:[code="sql"]SELECT cntr_value / 1024.0 AS TotalServerMemoryMBFROM sys.dm_os_performance_countersWHERE counter_name = 'Total Server Memory (KB)';[/code]For physical (if VM host is stealing) and buffer use:[code="sql"]SELECT CAST(physical_memory_in_bytes / (1024.0 * 1024.0 * 1024.0) AS DECIMAL(20, 2)) AS PhysicalMemoryGB, CAST((bpool_committed * 8) / (1024.0 * 1024.0) AS DECIMAL(20, 2)) AS BufferPoolCommittedMemoryGBFROM sys.dm_os_sys_info;[/code]Thu, 20 Sep 2012 14:57:27 GMTopc.threehttp://www.sqlservercentral.com/Forums/Topic1362292-1550-1.aspxI have a 8GB SS2K8 database on a smallish VMware server with 5 other VMs running on the host. The SS2K8 server is supposed to have 4GB of memory. Task Manager and Activity monitor indicate that there is 4GB, but I suspect that the host is stealing memory for another VM because a few times a day the database slows way down. I don't see high IO or CPU on the database when this happens. Are there DMV's that would allow me to view what the database is really getting ( or losing!) during these slow downs?Thu, 20 Sep 2012 13:43:49 GMTjberg-604007
