<div dir="ltr"><div><div>Hi,<br><br></div>Currently not all the supported hypervisor provides the memory usage information. The 'memory' meter therefore collects the amount of allocated memory from Libvirt and also Hyper-v. The other counter, 'memory.usage' gathers the actual usage information from VMware vCenter, so it also means that this meter is available only for this particular hyervisor.<br>
