Hi,
i am seeing regular cpu load spikes in the monitoring (zabbix, netdata), but can't find why. I have only 2 clusters with different use case, co can't compare with another. Some standalone PVE hosts has some regular spikes too, but it's not so visible so not 100% sure.
Those regular spikes are visible in a lot of the VMs (different types):
Even not used VM:
The first cluster ~20 min spike interval:
PVE 7.4-19 - all nodes with VMs, nfs and iscsi storage (spike's times are different per node)
7.4-19 - cluster node (in maintenance) without VMs, nfs and iscsi storage
The second cluster ~1:30 hod spike interval:
PVE 8.3.5 - node with VMs, ceph storage
Is there any PVE regular process with such effect? HA, storage, monitoring, etc etc? Or any hint what to check? I hoped netdata will show symptoms, but nothing comparable on graphs.
Thanks.
