Hello,
I enabled the data deduplication feature on a 2012 Windows server but I've noticed the volume monitoring is no longer working correctly:
Windows shows 186GB free on the E: volume since dedup has been running:

SolarWinds is only showing 13.9GB available:

And here you can see where I enabled dedup in Windows. The graph suddenly goes to 0%:

The server is being monitored via SNMP.
Has anyone else noticed this? Is this a SolarWinds issue or is it SNMP on the Windows server that doesn't understand dedup?
Thanks.
