            <title>[SERVER-71480] Reduce logging frequency of &quot;Slow session workflow loop&quot;</title>
                <link>https://jira.mongodb.org/browse/SERVER-71480</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;On a completely idle mongod, this log message is reported every 10 seconds:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;{&quot;t&quot;:{&quot;$date&quot;:&quot;2022-11-18T15:01:48.159+01:00&quot;},&quot;s&quot;:&quot;I&quot;,  &quot;c&quot;:&quot;EXECUTOR&quot;, &quot;id&quot;:6983000, &quot;ctx&quot;:&quot;conn1&quot;,&quot;msg&quot;:&quot;Slow SessionWorkflow loop&quot;,&quot;attr&quot;:{&quot;elapsed&quot;:{&quot;totalMillis&quot;:10010,&quot;activeMillis&quot;:10010,&quot;receiveWorkMillis&quot;:0,&quot;processWorkMillis&quot;:10007,&quot;sendResponseMillis&quot;:3,&quot;finalizeMillis&quot;:0}}}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;It seems like the intention of this log message is to indicate an abnormality, but it is actually being logged in the steady state of the system. We should avoid logging it so frequently.&lt;/p&gt;</description>

                            <comment id="5005052" author="blake.oler" created="Wed, 23 Nov 2022 21:13:21 +0000"  >&lt;p&gt;Seeing this log message every ten seconds on a connection that lasts ten seconds makes sense &amp;#8211; the threshold is 100ms to make a slow &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6240ef6c4607089b546e178a4d5d1f9beea36848/src/mongo/db/server_options.h#L80&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;operation&lt;/a&gt; (and its underlying connection!).&lt;/p&gt;

&lt;p&gt;I&apos;d actually say that the log isn&apos;t the issue here &amp;#8211; why do we have an operation that sits around for ten seconds? Should such an operation be excluded from the slow SessionWorkflow log catcher?&lt;/p&gt;

&lt;p&gt;I&apos;m interested in seeing the logs for this.&lt;/p&gt;

&lt;p&gt;This is all mainly a moot point, though &amp;#8211; &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71029&quot; title=&quot;Update slow SessionWorkflow log criteria&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71029&quot;&gt;&lt;del&gt;SERVER-71029&lt;/del&gt;&lt;/a&gt; will restrict this log to only emit when the &lt;tt&gt;sendResponse&lt;/tt&gt; (read: networking) phase is over 100ms, and even then we&apos;ll only emit a log at most once every five seconds. We should only run into this saturation point on a severely overloaded system.&lt;/p&gt;

&lt;p&gt;I&apos;m closing this as resolved by/a duplicate of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71029&quot; title=&quot;Update slow SessionWorkflow log criteria&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71029&quot;&gt;&lt;del&gt;SERVER-71029&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;</comment>
