            <title>[DOCS-16200] [SERVER] Investigate changes in SERVER-34633: Allow $currentOp to retrieve operations from all members of each shard in a cluster</title>
                <link>https://jira.mongodb.org/browse/DOCS-16200</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 an option to $currentOp stage. {$currentOp: {targetAllNodes: val}} where if val is true, currentOp outputs a document for every data bearing node for all shards. (If there are 3 shards, each a 3 node replica set, we will get 9 docs). If val is false, currentOp outputs a document for every shard.&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;    With the introduction of the &lt;tt&gt;$currentOp&lt;/tt&gt; aggregation stage, users have the ability to obtain a list of operations running on Secondaries in a sharded cluster by setting the appropriate &lt;tt&gt;readPreference&lt;/tt&gt;. However, this will only provide the operations from a single eligible Secondary in each shard, and the standard approach to more fine-grained targeting - using replica set tags - is both onerous and does not satisfactorily address this shortcoming.&lt;/p&gt;

&lt;p&gt;Add a new flag to &lt;tt&gt;$currentOp&lt;/tt&gt; which, if set, stipulates that it should target every data-bearing member in each shard and return an exhaustive list of all operations running anywhere in the cluster.&lt;/p&gt;
