Im looking to capture low and out-of-memory conditions by querying sys.dm_os_ring_buffers
reference this blog post
http://blogs.msdn.com/b/mvpawardprogram/archive/2012/06/04/using-sys-dm-os-ring-buffers-to-diagnose-memory-issues-in-sql-server.aspx
The query just looking at RING_BUFFER_RESOURCE_MONITOR, but I want to change the where filter.
Can I filter on both buffer types, as long as the messages are the same format/schema?
like this?
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(ms, -1 * dosi.ms_ticks - rb.timestamp, GETDATE()) AS RmDateTime
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;
