<p>The memory labels were updated -I think- since xymon-4.3.26.<br>
</p>
<p>The first label is for UNIX/Linux and the second for Windows boxes.<br>
</p>
<p><br>
</p>
<p>On our 4.3.27 server, a Windows 2012R2 server with 16GB memory reports like this:<br>
</p>
<p><br>
</p>
<p><span style="font-size: 9pt; font-family: Consolas, monospace;"><span style="font-family: Consolas, monospace;">Memory Used Total Percentage</span><br style="font-family: Consolas, monospace;">

the usage figure hard to understand (which is why "page/swap" used does not equal real used + actual used).

<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:blue">Also, some processes might be partially or totally swapped out of physical memory to the swap file, so you cannot say that Real used "is the sum total of memory
