      <description>&lt;P&gt;Dear All,&lt;/P&gt;
&lt;P&gt;I have to exclude a filesystem. Therefore, I need to know about the following questions:&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;Will the below rule exclude/not exclude the filesystem from the monitoring?&lt;/LI&gt;
&lt;LI&gt;Why do we have an alert and sample limit for the excluded filesystem?&lt;/LI&gt;
&lt;/UL&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Babar_Qayyum_0-1676197989890.png" style="width: 999px;"&gt;&lt;img src="https://community.dynatrace.com/t5/image/serverpage/image-id/9902iB25B910DAD315B81/image-size/large?v=v2&amp;amp;px=999" role="button" title="Babar_Qayyum_0-1676197989890.png" alt="Babar_Qayyum_0-1676197989890.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;Regards,&lt;/P&gt;
