            <title>[SERVER-18468] Include query planning details on query log lines</title>
                <link>https://jira.mongodb.org/browse/SERVER-18468</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The work completed for this ticket was to add two new fields to the slow query log lines and to the entries in the &lt;tt&gt;system.profile&lt;/tt&gt; collection:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;tt&gt;fromMultiPlanner&lt;/tt&gt; indicates whether or not multiple candidate plans were evaluated before choosing a winning execution plan for the query. This flag will be false if the query plan was generated based on a plan cache entry or if there was any a single possible execution plan. It will only appear in the log or in &lt;tt&gt;system.profile&lt;/tt&gt; if it has a value of &lt;tt&gt;true&lt;/tt&gt;.&lt;/li&gt;
	&lt;li&gt;&lt;tt&gt;replanned&lt;/tt&gt; indicates whether or not the CachedPlanStage replanning logic kicked in during the execution of this plan. For more details on replanning, see &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-15225&quot; title=&quot;CachedPlanStage should execute for trial period and re-plan if query performs poorly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-15225&quot;&gt;&lt;del&gt;SERVER-15225&lt;/del&gt;&lt;/a&gt;. The flag will only appear in the log or in &lt;tt&gt;system.profile&lt;/tt&gt; if it has a value of &lt;tt&gt;true&lt;/tt&gt;.&lt;/li&gt;
&lt;/ul&gt;


&lt;h4&gt;&lt;a name=&quot;OriginalDescription&quot;&gt;&lt;/a&gt;Original Description&lt;/h4&gt;

&lt;p&gt;Currently when looking at a query log line it&apos;s impossible to tell whether or not query planning happened.  This makes it hard to know if the query was slow for inherent reasons, or slow because planning occurred (and maybe many plans were tried).&lt;/p&gt;

&lt;p&gt;It would be great if the query log line could indicate whether or not query planning happened, and if so some basic stats about the planning stage, e.g. number of plans run, the w value of the winning (cached) plan (i.e. the number of &quot;work&quot;s required for the plan to win), whether or not the plan was cached (since sometimes it&apos;s not), etc.&lt;/p&gt;

&lt;p&gt;For example something like (spaces added for clarity only):&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;
