                <link>https://jira.mongodb.org/browse/DOCS-16384</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &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;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    serverStatus output now exposes metrics about readPreference. See this document for details about what is exposed: &lt;a href=&quot;https://docs.google.com/document/d/1GZK3Izg3PBjtjCv1aiptuHQzudHMZlxnO5IdtDBUVgc/edit#heading=h.jmjxxubeuhdo&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.google.com/document/d/1GZK3Izg3PBjtjCv1aiptuHQzudHMZlxnO5IdtDBUVgc/edit#heading=h.jmjxxubeuhdo&lt;/a&gt;&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    &lt;b&gt;Goal / Product Question:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Our recommended topology is a replica set with three nodes for high availability. However, some customers are questioning the cost associated with running all three nodes, where they claim reads &amp;amp; writes only happen on their primary.&lt;/p&gt;

&lt;p&gt;We offer the ability to redirect &lt;a href=&quot;https://www.mongodb.com/docs/manual/core/read-preference-use-cases/#read-preference-modes&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;reads to a secondary node&lt;/a&gt;. We believe there is a population of customers who use secondary reads, but we never had a good way to identify them. Exposing a metric to identify if a secondary node has served reads will help identify these customers who specifically directed reads to a secondary node.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Must have:&lt;/b&gt;&#160;&lt;/p&gt;

&lt;p&gt;-Number of clusters with secondary reads&lt;/p&gt;

&lt;p&gt;-Distribution of readPreference options (e.g. secondary, secondaryPreferred, primary)&#160;&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Nice to Have:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;-Hedge Reads&#160;&lt;/p&gt;

&lt;p&gt;-Mirror Reads&lt;/p&gt;

&lt;p&gt;-Number of clusters with reads with multiple read preferences&lt;/p&gt;
