XenServer ITCAM does not collect CPU and Memory utilization metrics

Hi Support team, this idea is follow-up for the Case TS004347982. XenServer ITCAM does not collect CPU and Memory utilization data from Citrix XenServer Management API. We received the following suggestion from L3 support:

Citrix eventually admit that


Reading CPU utilization using the API fields has been deprecated since Xenserver 6.1, and are no longer updated because this functionality has been replaced by RRD statistics:

fields for IO bandwidth as part of VIF_metrics, VBD_metrics, PIF_Metrics

class VBD_metrics

class VIF_metrics

field vCPU utilisation as part of VM_metrics

memory_free as part of host_metrics (was internally deprecated)

The deprecation is backdated to Xenserver 6.1 and no longer supported.


That means those deprecated fields in our XenServer (version : 7.1 Cu2 ) are not supported, and they suggested us to change to retrieve those values using RRD statistics API.
