I have been using Veeam One for some time now in testing and have only a week ago went full production and seem be either confused on a couple report/errors or they are mis-reporting data. The first one is the "Host Average Memory Pressure" . alert. I have two Hyper-V hosts, each with 192 GB of RAM and each host only lightly used. If I select one of the hosts and select the Memory tab, the Data is as follows:
Units Latest Min Avg Max
Hyper-V Services Memory Consumed GB 49.56 49.39 49.73 51.77
Hyper-V Services Memory Usage % 25.81 25.72 25.90 26.95
Memory Consumed GB 44.78 44.62 44.96 47.00
Memory Usage % 23.32 23.23 23.41 24.96
These metrics are, to me, very small. I have a couple VMs which periodically run into memory pressure issues, but not the hosts themselves and this alert is for the host itself. The second host is very close to this one as far as usage goes.
The second alert that confuses me is, for the VM itself, some will receive the "Hyper-V snapshot size" alert. We do not use snapshots as a practice so I am not understanding where this alert comes from. I will though, it only appears for VMs that have gone through a P2V migration. All other VMs do not reflect snapshot alerts
