oversized versus undersized

Hi,

In VeeamOne reporting there are templates for ovesized and undersized reports. When I run these reports for a time period of 3 months I get contradicting values for the same virtual machine.

Oversized
TNRAS167 4 2,38 4,76 4,00 0,66 1,32 3 2,30 Configure this VM with 1 vCPUs. Allocate 1.7 GBs of RAM.
Undersized
TNRAS167 4 2,38 0,00 4,00 0,66 0,08 Allocate not less than 5.1 GBs of RAM.

Could you explain what is happening why the report for oversize says I have to allocate 1.7GB and the unsized says I have to allocate at least 5.1GB. Both reports have run in the same time frame and period.

Kind regards,
Dave

Hi Dave,

What is the memory swap out rate for your VM? Is it 0,08 Kbps? Let me ask our QC team to try to reproduce this VM behavior.

Thanks!

Hi Vitaliy,

Yes the swap out rate is 0,08.

I have other examples from a different vm:

Oversized
TNRAS013 2 9,05 34,13 4,00 2,31 2,74 1 0,50 Configure this VM with 1 vCPUs. Allocate 3.5 GBs of RAM.
Undersized
TNRAS013 2 9,05 0,20 4,00 2,31 0,02 Allocate not less than 5.1 GBs of RAM.

Kind regards,

Looks like we've been able to confirm this, thanks for bringing this to our attention. The reason why you had two VMs present in the reports is that under certain conditions VM memory usage was not calculated properly for undersized VMs report. I've already passed this info to our dev team. Thanks!
