This T-SQL script reads that buffer to produce a CPU history report showing SQL Server CPU usage, other process CPU usage, and total server CPU load — without requiring any external monitoring tool.</p> <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-1012089347386563" crossorigin="anonymous"></script> <ins class="adsbygoogle" style="display:inline-block;width:728px;height:90px" data-ad-client="ca-pub-1012089347386563" data-ad-slot="8593449130"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> <h2 id="purpose-and-overview">Purpose and Overview</h2> <p>When a CPU spike occurs on a SQL Server host, the first question is whether SQL Server caused it or whether another process did. The <code>sys.dm_os_ring_buffers</code> DMV stores CPU statistics that SQL Server collects from the Windows performance counters every 60 seconds, retaining the last 256 minutes of data.</p>
