            <title>[SERVER-25143] Output disk read and write metrics in system-independent units</title>
                <link>https://jira.mongodb.org/browse/SERVER-25143</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The new system metric diagnostic data for disks has &quot;read_sectors&quot; and &quot;write_sectors&quot;, but &quot;sector&quot; is a system-specific unit, and can possibly vary between filesystems. This field should be converted to a non-system-specific unit, preferably bytes.&lt;/p&gt;</description>

                            <comment id="1343175" author="mark.benvenuto" created="Mon, 1 Aug 2016 15:57:06 +0000"  >&lt;p&gt;The &quot;sectors&quot; that are listed in the disk data come from &lt;tt&gt;/proc/diskstats&lt;/tt&gt;. These same counters can be found in &lt;tt&gt;/sys/block/&amp;lt;x&amp;gt;/stat&lt;/tt&gt;. The &quot;sectors&quot; field is in system-independent 512 byte increments. It is a simple transformation to multiple sectors by 512 in order to return bytes.  To quote the documentation:&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;read sectors, write sectors&lt;br/&gt;
===========================&lt;/p&gt;

&lt;p&gt;These values count the number of sectors read from or written to this&lt;br/&gt;
block device.  The &quot;sectors&quot; in question are the standard UNIX 512-byte&lt;br/&gt;
sectors, not any device- or filesystem-specific block size.  The&lt;br/&gt;
counters are incremented when the I/O completes.&lt;/p&gt;&lt;/blockquote&gt;
