            <title>[SERVER-80173] Write $currentOp Metrics for Resharding at End of Operation</title>
                <link>https://jira.mongodb.org/browse/SERVER-80173</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, resharding tracks metrics via &lt;a href=&quot;https://github.com/mongodb/mongo/blob/304df008fa15062c38dad841699009b1d9e7bf31/src/mongo/db/s/resharding/resharding_metrics.h#L179&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ReshardingMetrics&lt;/a&gt; reported in &lt;a href=&quot;https://www.mongodb.com/docs/v6.2/reference/operator/aggregation/currentOp/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;$currentOp&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/304df008fa15062c38dad841699009b1d9e7bf31/src/mongo/db/s/resharding/resharding_cumulative_metrics.h#L73&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ReshardingCumulativeMetrics&lt;/a&gt; (via its &lt;a href=&quot;https://github.com/mongodb/mongo/blob/304df008fa15062c38dad841699009b1d9e7bf31/src/mongo/db/s/metrics/sharding_data_transform_cumulative_metrics.h#L109&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;base class&lt;/a&gt;) reported in &lt;a href=&quot;https://www.mongodb.com/docs/manual/reference/command/serverStatus/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;serverStatus&lt;/a&gt;. Because the serverStatus command returns metrics from the whole host in aggregate, it&apos;s difficult to capture metrics that are specific to a particular operation. As such, there are some metrics (e.g. duration spent in each phase) that are only reported by $currentOp. However, $currentOp is only available while the operation is still running, which limits its usefulness when trying to do analysis after the fact. Therefore, we should log the BSON object returned by reportForCurrentOp() at the end of the resharding operation.&lt;/p&gt;</description>
