Windows Server 2016, 32GiB RAM.
I just added two Windows 2016 servers to Zabbix monitoring (5.0.2 server and 5.02 Agent1 / not using Agent2), and both show 0% swap space free:
However, if I go onto the server and use WMIC to check for swap (pagefile) utilization, I get this:
This is unsurprising, as the server in question is provisioned with 32GiB of RAM and is only using about 11GiB, as reported by TaskMangler:
If I kick up the debug level on the agent to '5', this is what I get in the logs there:

Looks like there is some problem with the agent getting the correct swap utilization info via WMI. This is only occurring on two of my Windows 2016 servers. The differences between these servers and others in my environment are the RAM provisioning (exactly 32GiB) and they're running Microsoft Exchange 2016 (probably unrelated). I have servers with more RAM and less RAM being monitored that do not have this issue.
