Unsolved Zabbix gone wild

That's right in the middle. Seems like it might have been growing and shrinking. That's a fairly common thing to have happen during certain processes.
Unless it's a busy VM, +/- 12% at a time is kinda crazy.

Cache
I could easily see 10/12% of RAM being a cache but 10% of your disk space... depending on the size of the disk, that could still be huge (not to mention slow).

What if it is a cache of logs being compressed or something similar?
-
Or temporary database tables?

The plot thickens. This is the 12 hour graph:
You can see when I added space, but it still keeps going up and down. I'm going to restart the zabbix service.
-
@Mike-Davis What kind of server is this?
-
@dafyre It's a remote desktop server. I have one user on it now. I'm going to bounce it in a little bit when they are finished.
-
Users could be doing nearly anything in that case.

Temporary Database Tables... or user causing issues... You can guess which one I'd pick as the problem.
-
@scottalanmiller I would agree, except I don't think anyone was on at 3:00 AM, and there is only one user on now, and that is another Admin.

You can track RD sessions for that in Zabbix. You have to nab them with perf_counter.
-
The thing is, I'm on the server and I can see free space and it's not changing. The Zabbix graph thinks it is though. I'll launch perfmon to see if it's changing faster than I can see it.
-
Perfmon shows it steady with 37% free. So it must be Zabbix.
-
Weird.
-
Even after a reboot, Zabbix is still seeing the same thing. It's not kicking out emails, which is also odd.

What version of Zabbix Server & Agent?
Also, what is the Zabbix key (Configuration -> Hosts -> Host -> Items) it is looking at?
-
@dafyre It looks like: Triggers 1 vfs.fs.size[C:,pfree]
-
What version of Zabbix agent and server?
What version of Windows Server?
-
@dafyre It's Zabbix Server 3.2
Zabbix Agent Version 3.2.0.62444Windows Server 2012 R2 patched up to date. It has the RDS role and RDS gateway role installed on it.
-
From your Zabbix server...
try to run this command a few times and see if it returns everything like it should:
zabbix_get -s ipofyourhost -k "vfs.fs.size[C:,pfree]"Run it a few times back-to-back and see what you get... and then compare with the results of...
zabbix_get -s ipofyourhost -k "vfs.fs.size[C:,free]"
