This isnt an “Error Message” as much as it seems that when vMotions occur the VM is marked as missing for like 10 seconds so we’re flooded with a lot of up/down messages. Since this is essentially a brand new install and the defaults I figured I would hear of others with this issue, but I havent found any other posts describing this.
we had the same problem when monitoring vmware VMs directly through the host and not the vcenter.
What helped for us:
Create A Cluster in the same folder like the esx hosts (Hosts → Add Cluster)
add your esx to this cluster
Create a rule in “Cluster Services” - Condition should be the folder where your esx hosts and the Cluster Object is. Also Set Filter for Services - “VM .*” worked for us.
create a “Aggregation options for clustered services” rule. Choose “Explicit host” and set it to the cluster object. Aggregation option should be “best node wins”.
run a service distovery on the esx-host objects. all the VMs should go to the “Monitored clustered services - located on cluster host” section
run a service discovery for the cluster object you created - all the VMs from all the hosts should appear here
