Hi,
after upgradeing our CS agents to 4.17 we see in our logfiles some errors
and warnings.
Hosts are running ubuntu 20.04 - latest patches applied.
First:
After start / restart of the Agent we are getting errors that the Agent
can't get the CPU values:
2022-08-28 13:36:51,849 INFO [utils.linux.KVMHostInfo]

(Agent-Handler-1:null) (logid:) Using the value [1803] provided by Libvirt.
How ever it seems that values from libvirt are provided.
More "concerning" ist the following warnings from the logfiles:
[kvm.resource.LibvirtComputingResource] (agentRequest-Handler-3:null)
(logid:44ab098e) Couldn't retrieve free memory, returning -1.
Some kind on advice / how solve these would be wonderful.
regards,
chris
