            <title>[SERVER-16176] Log slow checkpoints under WiredTiger</title>
                <link>https://jira.mongodb.org/browse/SERVER-16176</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Under mmapv1, slow background flushes are logged, and this can be useful for diagnosing some performance issues. The equivalent in WiredTiger, slow checkpoints, are not logged (although summary statistics are or will be available); it would be useful to have them logged as well.&lt;/p&gt;</description>

For the new stats, see &lt;a href=&quot;https://github.com/wiredtiger/wiredtiger/issues/1374&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/wiredtiger/wiredtiger/issues/1374&lt;/a&gt;.&lt;/p&gt;</comment>
