            <title>[COMPASS-6704] Investigate changes in SERVER-70025: add serverStatus metrics planCacheHits and planCacheMisses</title>
                <link>https://jira.mongodb.org/browse/COMPASS-6704</link>
                <project id="13182" key="COMPASS">Compass </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;    We added 4 new serverStatus metrics to count hits and misses in the classic and SBE plan caches. They are:&lt;/p&gt;

&lt;p&gt;query.planCache.classic.hits&lt;br/&gt;
query.planCache.classic.misses&lt;br/&gt;
query.planCache.sbe.hits&lt;br/&gt;
query.planCache.sbe.misses&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;    Inspired by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64978&quot; title=&quot;Add metrics to track if a plan was recovered from the plan cache&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64978&quot;&gt;&lt;del&gt;SERVER-64978&lt;/del&gt;&lt;/a&gt;, we should add two additional serverStatus metrics counters to accumulate plan cache hits and misses. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=christopher.harris%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;christopher.harris@mongodb.com&quot;&gt;christopher.harris@mongodb.com&lt;/a&gt; has confirmed this would be useful for product/field team.&lt;/p&gt;
