[ovirt-users] How to deal with "Used memory of host ... exceeded defined threshold [95%]" messages

Hi,
I'm trying to figure out how I could stop the manager with spamming
used memory exceeded threshold messages. I have a hypervisor that has
1,5TB memory and it's using about 98% of that with hugepages for sap
hana vms (configured like https://access.redhat.com/articles/3347431).
It still has like 40-50GB memory left for the hypervisor which should
be plenty.
So the option I could figure out on my own: I can adjust the global
limit of LogMaxPhysicalMemoryUsedThresholdInPercentage but I'm not
sure if that is a good idea for my "normal" hypervisors that often
have way less memory.
My questions are:
- can I adjust the limit on a per hypervisor basis?
- can I skip the memory check for certain hypervisors or skip all
checks for certain hypervisors?
- would a check for free memory in gb make more sense than a percentage check?
Setup is still on 4.1.9.
Greetings
Klaas
