            <title>[DOCS-15832] Investigate changes in SERVER-46446: Log time spent waiting for remote operations</title>
                <link>https://jira.mongodb.org/browse/DOCS-15832</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;    This change adds a new optional field, &quot;remoteOpWaitMillis&quot; to the profiler / slow query log lines.  It tells you how much time the node spent waiting for results from other nodes.  By comparing this with the total &quot;durationMillis&quot; you can figure out whether the merger or a shard is to blame for a slow query.&lt;/p&gt;

&lt;p&gt;This change basically expands &apos;remoteOpWaitMillis&apos; to any command that contacts shards.&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;    This ticket is the find() counterpart of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-31368&quot; title=&quot;Log time spent waiting for other shards in merge cursors aggregation stage&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-31368&quot;&gt;&lt;del&gt;SERVER-31368&lt;/del&gt;&lt;/a&gt; which addresses aggregation.&lt;/p&gt;
