            <title>[GODRIVER-3095] Add moving STD to RTT Stats</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-3095</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;h3&gt;&lt;a name=&quot;Context&quot;&gt;&lt;/a&gt;&lt;b&gt;Context&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;Qualify the connection stability by providing the user with the moving standard deviation in the &lt;a href=&quot;https://github.com/mongodb/mongo-go-driver/blob/c1b1a4f544874622b58d16a18fc2751154093b51/x/mongo/driver/topology/rtt_monitor.go#L300&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;rttMonitor.Stats()&lt;/a&gt; method, which will likely the propagated as an operation error during a timeout.&lt;/p&gt;

&lt;p&gt;This value should be the average standard deviations of the &lt;tt&gt;S_{10&lt;/tt&gt;} moving average defined &lt;a href=&quot;https://mathworld.wolfram.com/MovingAverage.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;. Which would result in a Nx1 vector of standard deviations, like &lt;a href=&quot;https://www.mathworks.com/help/matlab/ref/movstd.html#d126e1035934&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Here is a working example, you can roughly confirm the hypothesis by adjusting the &lt;tt&gt;rang&lt;/tt&gt; variable which should grow larger by a factor of itself: &lt;a href=&quot;https://go.dev/play/p/s54Z4BQWPCR&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://go.dev/play/p/s54Z4BQWPCR&lt;/a&gt;&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;Definitionofdone&quot;&gt;&lt;/a&gt;&lt;b&gt;Definition of done&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;Implement the moving standard deviation for rtt samples.&lt;/p&gt;</description>
