Veeam ONE fails to collect performance data from one or multiple Hyper-V hosts despite being able to collect infrastructure and topology data. This issue may occur with or without an alarm being triggered. When an alarm is triggered, it will display the message: Performance data collection failure - object <hv_host> Veeam ONE Monitoring Server failed to collect performance data from the objects specified.
Any of the following could cause this: Insufficient permissions for the account used by Veeam ONE to collect the data from the Hyper-V host. Services which Veeam ONE relies on are not running on the Hyper-V host. No performance data is available in the Microsoft Performance monitor on the Hyper-V host due to corrupt, modified, or missing Windows performance counters or performance counter sets on the host system. Third-party applications can also be responsible for changing the default Performance Monitor counter set configuration.
Permissions Ensure that the account Veeam ONE uses to connect to the Hyper-V host(s) has the required permissions, or change the server connection settings to assign a different account.
