            <title>[DOCS-15652] [SERVER] Investigate changes in SERVER-64967: Measure how long it takes operations using egress connections to write to network</title>
                <link>https://jira.mongodb.org/browse/DOCS-15652</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 adds a new serverStatus metric that is guarded under the featureFlagConnHealthMetrics feature flag:&lt;/p&gt;

&lt;p&gt;&apos;metrics.network. totalTimeForEgressConnectionAcquiredToWireMicros&apos;:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;The time taken for an operation to acquire an egress connection and complete writing to the wire. This metric is cumulative across all such connections since the last server restart.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Also a new server parameter was added: &apos;connectionAcquisitionToWireLoggingRate&apos;:&lt;br/&gt;
    description: &amp;gt;-&lt;br/&gt;
        The rate at which egress connection metrics below a certain time threshold will be logged at&lt;br/&gt;
        info level. This only applies for the &apos;network.totalConnectionAcquiredToWireMillis&apos;&lt;br/&gt;
        server status metric.&lt;/p&gt;

&lt;p&gt;This server parameter is settable at startup and on runtime. The default value is 0.2. Values must be between 0.0 and 1.0.&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;    We sometimes see operations get bottlenecked at the point in their lifecycle where they need to perform RPC. In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64964&quot; title=&quot;Measure egress connection creation time from connection pools&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64964&quot;&gt;&lt;del&gt;SERVER-64964&lt;/del&gt;&lt;/a&gt;, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64965&quot; title=&quot;Count the number of operations that fail due to timing out waiting to acquire a connection&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64965&quot;&gt;&lt;del&gt;SERVER-64965&lt;/del&gt;&lt;/a&gt;, and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-63261&quot; title=&quot;Add metrics for wait time for requests to acquire egress connections&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-63261&quot;&gt;&lt;del&gt;SERVER-63261&lt;/del&gt;&lt;/a&gt;, we&apos;re adding metrics to measure how long connection establishment takes, how many operations fail while waiting to acquire connections, and how long operations spend waiting to acquire connections.&lt;/p&gt;

&lt;p&gt;For completeness, let&apos;s also measure the amount of time operations spend doing networking after they acquire a connection. Add a measurement of how much wall-time passes between an operation acquiring a connection and it completes writing to the wire.&#160;&lt;/p&gt;
