5.7.1 VR usage of NF

5.7.1.1 Virtual CPU usage

5.7.1.1.1 Mean virtual CPU usage

a) This measurement provides the mean usage of the underlying virtualized CPUs for a virtualized 3GPP NF. This measurement is not applicable to the scenario that one VNFC instance supports more than 1 NFs.

b) OM.

c) The measurement job control service producer for NF(s) receives the VcpuUsageMeanVnf.vComputeId measurement(s) (see ETSI GS IFA 027 [17]) for the VNFC instances(s) from VNFM, and maps the measured object of each received measurement from VNFC instance to the MOI(s) of NF(s). The measurement is generated by taking the weighted average of the values of the VcpuUsageMeanVnf.vComputeId measurement(s) whose measured object(s) are mapped to the MOI of the measured NF. The algorithm of the weighted average is vendor specific.

d) A single integer value (Unit: %).

e) VR.VCpuUsageMean
