Wrong RAM size reported

[jackburton79]

For some servers (the ones with big amount of RAM) NSClient++ reports a smaller amount of physical memory than the one installed.
This server, for example, has 36GB

But nsclient (when queried with check_nscp_api) reports only 30GB.

[stefano@monitoring ~]$ '/usr/lib64/nagios/plugins/check_nscp_api' '--password' '' '-H' '' '-P' '****' '-q' 'check_memory'
check_memory WARNING: committed = 30.843GB, physical = 30.493GB | 'committed'=30.843372GB;31.999649;35.999605;0;39.999561 'committed %'=77%;80;90;0;100 'physical'=30.4934
08GB;28.799649;32.399605;0;35.999561 'physical %'=85%;80;90;0;100

If I remember correctly, when I was using check_nt it reported it correctly.

Details

• NSClient++ version: 0.5.2041
• OS and Version: Windows Server 2012R2 (but on 2016 is the same)
• Checking from: Icinga2
• Checking with: check_nscp_api

Note that also running check_memory from NSClient++ test mode returns the wrong amount of memory:
check_memory

Here's also a screenshot of the VM definition

checkmem, instead, seems to return the full memory capacity, pagefile included:
