Host Memory Pages Usage Confusion (Hyper-V Host)

[Murigar]

Can anyone help me understand why I am seeing a lot "Host Memory Pages Usage" alerts in my 4 node Hyper-V cluster?
They are alerting at all times of the day. Not only during backup.
There are no other repeating alerts being generated.

Memory Usage%, Hyper-v Services Memory Usage %, & Average Pressure%, as reported by Veeam One does not exceed 50% on any host.
There appears to be lots of free memory. (Hosts have 768GB memory ea.)

Page Faults/sec is roughly between 2000-5000 on three hosts, the forth 7000 - 13000.

Memory Swap rate is zero to 10. Occasional momentary spikes during backup jobs.

Thank you for your time.

Hi Murigar,

If you haven’t already, I’d recommend opening a support case and sharing the case # here so we can take a closer look.

In general, we don’t usually have reasons to doubt the data sources Veeam ONE relies on. However, Support can verify where exactly these metrics are coming from and confirm whether they are expected from a monitoring perspective.
If the values are caused by a third‑party component, Support won’t be able to fix that directly, but they should still should be able to identify and validate the data.

Thanks

Hi, I am noticing the same problem, I just switched to Hyperv 2025 with a server with 128 GB of RAM, I have only one VM loaded with Windows Server without services and it gives me the exact same error. Which version of Hyperv are you using?

@ MTIK I am using Hyper-V 2022.

Hello,
Did any of you manage to create a support ticket so we can take a look at the logs, and escalate it if appropriate?

Thank you!
