    <description>&lt;P class=""&gt;Hi Dynatrace Team,&lt;/P&gt;&lt;P&gt;We have configured &lt;STRONG&gt;CPU anomaly detection / CPU saturation&lt;/STRONG&gt; with a custom threshold of &lt;STRONG&gt;70% CPU usage&lt;/STRONG&gt;.&lt;/P&gt;&lt;P&gt;However, when a CPU Saturation problem is generated, the Problem page shows:&lt;/P&gt;&lt;BLOCKQUOTE&gt;&lt;P&gt;&lt;STRONG&gt;CPU idle threshold below 5%&lt;/STRONG&gt;&lt;/P&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;Please refer to the attached screenshot.&lt;/P&gt;&lt;P&gt;For example, for host &lt;STRONG&gt;dr-ibps-db01&lt;/STRONG&gt;, the Problem page shows &lt;STRONG&gt;CPU Saturation – CPU idle threshold below 5%&lt;/STRONG&gt;, while the CPU usage shown in the graph is mostly around &lt;STRONG&gt;60–82%&lt;/STRONG&gt;.&lt;/P&gt;&lt;P&gt;We would like to understand the following:&lt;/P&gt;&lt;OL&gt;&lt;LI&gt;Why is the Problem page showing &lt;STRONG&gt;“CPU idle threshold below 5%”&lt;/STRONG&gt; instead of our configured &lt;STRONG&gt;70% CPU usage threshold&lt;/STRONG&gt;?&lt;/LI&gt;&lt;LI&gt;Are &lt;STRONG&gt;CPU anomaly detection at 70%&lt;/STRONG&gt; and &lt;STRONG&gt;CPU Saturation (CPU idle below 5%)&lt;/STRONG&gt; separate detection mechanisms?&lt;/LI&gt;&lt;LI&gt;If the CPU usage crosses &lt;STRONG&gt;70% but does not reach 95%&lt;/STRONG&gt;, should Dynatrace generate a CPU anomaly/problem?&lt;/LI&gt;&lt;LI&gt;Which configuration controls the &lt;STRONG&gt;“CPU idle threshold below 5%”&lt;/STRONG&gt; displayed in the Problem page?&lt;/LI&gt;&lt;LI&gt;Is the &lt;STRONG&gt;5% CPU idle threshold equivalent to approximately 95% CPU utilization&lt;/STRONG&gt;, and is this the default CPU Saturation threshold?&lt;/LI&gt;&lt;LI&gt;If we want CPU Saturation to trigger at &lt;STRONG&gt;70% CPU utilization&lt;/STRONG&gt;, which setting should we modify?&lt;/LI&gt;&lt;/OL&gt;&lt;P class=""&gt;Could you please clarify how the &lt;STRONG&gt;70% threshold&lt;/STRONG&gt; and &lt;STRONG&gt;5% CPU idle threshold&lt;/STRONG&gt; are related and why the Problem page is displaying the latter?&lt;/P&gt;&lt;P&gt;Thanks in advance for your help.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
