            <title>[DOCS-13884] Investigate changes in SERVER-48742: Log whenever profiler settings are changed via setProfilingLevel</title>
                <link>https://jira.mongodb.org/browse/DOCS-13884</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;
&lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;We now log whenever the profile settings (level, slowms, sampleRate, filter) change at runtime (which happens via the profile command).&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;

&lt;p&gt;We should add a log message, at log level 0, whenever the server&apos;s profiling settings are changed at run-time. The typical way you change these settings is via the setProfilingLevel shell helper: &lt;a href=&quot;https://docs.mongodb.com/manual/reference/method/db.setProfilingLevel/index.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/method/db.setProfilingLevel/index.html&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;This will make it easier to understand log files. The server logs slow queries to the log file, using the profiling setting to decide what &apos;slow&apos; means. For someone digging through a log file, and seeing the number of slow queries suddenly go up or down, it might be helpful to know whether that&apos;s because the workload changed or the profiling settings changed.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;

&lt;p&gt;Suggest updating &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/profile/#behavior&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/command/profile/#behavior&lt;/a&gt; and &lt;a href=&quot;https://docs.mongodb.com/manual/reference/method/db.setProfilingLevel/index.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/method/db.setProfilingLevel/index.html&lt;/a&gt; to reflect this new behavior, along with the usual release notes update. There may be other places to doc this behavior, but those are the first pages which come to mind.&lt;/p&gt;
