I installed Veeam ONE and it's monitoring 3 hosts, 2 ESX 4.0 hosts and a ESXi 5.0 host
Both ESX 4.0 are reporting lots of event data collection failure, host connection failure, topology collection failure, Hardware sensors collection failure.
In the vSphere client, the two ESX host are reports their sensors as normal
The ESX 5.0 host seems normal
Is it an issue with ESX 4.0 ?
