Vitaliy S. wrote:How often do you see this situation? Is it specific to some platform (Hyper-V/vSphere)?
Shestakov wrote:Once you install Veeam ONE, give it some time to download historical data to show. It can take time depending on the infrastructure size.
Another possible reason is a lack of data or if the host was powered-off/disconnected.
Do you experience it just after the installation?

adiaz wrote:I've been delving a little and definitely I often get Performance Data Collection Failure alarms, but until now I have not been able to see them because the technician who installed Veeam disabled them. So probably it's a data collection issue, but I don't know how to fix it.

Shestakov wrote:That`s not a good practice to disable alarm if you can`t resolve it. There is Knowledge Base for each alarm with the issue description and resolution steps. If you or customer can`t resolve it, it`s highly recommended to contact technical support team.
Shestakov wrote:Do you generate it from Veeam ONE Monitor or Reporter? What is the name of the report?
Shestakov wrote:By the way, do you have these performance gaps for ESX(i) or Hyper-V hypervisor?
Vitaliy S. wrote:The best thing to do in this case is to monitor this alarm and when it happens try to resolve connection issues
Shestakov wrote:That`s interesting. Could you describe the issue a bit?
Shestakov wrote:Do you have Veeam ONE server installed on a VM running on the hypervisor which has the performance gaps?
Shestakov wrote:Does it miss particular metrics or all the performance?
