Memory issue

[Bart Brouwer]

Hello, i have proxmox 4.4-12/e71b7a74 installed.
i have 2 ubuntu VM's on the same server with unifivideo installed.
UnifiVideo works fine, but proxmox shows some strange things.

Into proxmox he gaves 4.8GB from 5 GB ram.
But with webmin and unifi software, he gaves 1.1 used (this look likes better)

Who could help me to understand this 'problem'? watch the upload file

tnx
Bart

If there is once some contest for "the most frequently asked question", this one might win it! Honestly, did you ever use "search" function, here or google? OK, forget it. Just point your browser here, read it and check your last picture again!

tnx for your quick reaction. I have red this on different pages. But why gives different application different answers?
but oke i will watch into the NVR next time and dont use proxmox for this.

Apparently, different applications understand free memory differently. But all apps should clearly distinguish between "free" and "available" memory. Problem is some older versions of "free" command do not show available memory (they show +/-buffers/cache instead). That's confusing...

I changed the PRTG settings for better monitoring
