            <title>[SERVER-23409] Add tunability to tcmalloc serverStatus detail</title>
                <link>https://jira.mongodb.org/browse/SERVER-23409</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-23069&quot; title=&quot;Improve tcmalloc freelist statistics&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-23069&quot;&gt;&lt;del&gt;SERVER-23069&lt;/del&gt;&lt;/a&gt;, the size of the TCMalloc section in &lt;tt&gt;serverStatus&lt;/tt&gt; has grown substantially with the addition of per-size class statistics (roughly 10-11 kB). This negatively affects FTDC data retention.&lt;/p&gt;

&lt;p&gt;It would be nice to be able to tune the level of detail with which we get TCMalloc statistics; for example,&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;tt&gt;tcmalloc: 1&lt;/tt&gt; returns the original level of detail prior to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-23069&quot; title=&quot;Improve tcmalloc freelist statistics&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-23069&quot;&gt;&lt;del&gt;SERVER-23069&lt;/del&gt;&lt;/a&gt; without size class information;&lt;/li&gt;
	&lt;li&gt;&lt;tt&gt;tcmalloc: 2&lt;/tt&gt; includes additional size class information;&lt;/li&gt;
	&lt;li&gt;&lt;tt&gt;tcmalloc: 3&lt;/tt&gt; includes the TCMalloc `DumpStats` text blob;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;and so on. (This behavior would also be backwards-compatible for people already specifying &lt;tt&gt;tcmalloc: 1&lt;/tt&gt; to &lt;tt&gt;serverStatus&lt;/tt&gt;.)&lt;/p&gt;</description>
