Prism appears to report the memory usage of our Linux (Ubuntu) guests incorrectly.
The user interface shows that 94% of memory is used:
Whereas the linux agent is showing 21GB is available.
root@build1:/home/user# free -h total used free shared buff/cache availableMem: 31G 9.2G 292M 8.8M 21G 21GSwap: 11G 66M 11GTechnically, the memory is being used, but the os would allow the applications to use more RAM if they need to (see the below link for reasons why).
The "Available" memory information would be useful to display in order to allow administrators to easily see the actual usage of their VM requirements, and make judgements as to whether their VMs are over or underprovisioned.
FWIW our ubuntu version is:
