VM CPU POOL report

This report provides monitored data for CPU pools.

Report output

The REPORT VM_CPU_POOL statement is used to request the output of the VM CPU POOL report. The report can only be output if the SM2 administrator has activated the monitoring process using the statement START-MEASUREMENT-PROGRAM TYPE=*VM.

The values for all CPU pools are only output if SM2 is running on the monitor VM. If this is not the case, only the values for the CPU pool which is assigned to the VM on which SM2 is running are output.

Overflow screens may also be requested for this report.

Monitoring information

CPU POOL	Name of the CPU pool
# CPUS	Number of real CPUs, available to BS2000 guest systems (also extra CPUs) which are assigned to the CPU pool
The following CPU values relate to the CPU-pool-specific TOTAL TIME, i.e. the total CPU time made available by the CPU pool during a monitoring cycle.
The following applies: TOTAL TIME = CYCLE * # CPUS with CYCLE = duration of the monitoring interval
HPV CPU (%)
ACT	Percentage of TOTAL TIME spent by the hypervisor in active time
IDLE	Percentage of TOTAL TIME accounted for by hypervisor IDLE time
CPU (%)	Percentage of TOTAL TIME accounted for by the CPU time of all BS2000 VMs which are assigned to the CPU pool

If a CPU pool runs in the scheduling mode “dedicated CPUS” (DC) (see SHOW-VM-CPU-POOL INF=*STD) and one or more VMs of the assigned pool use the mode VM-ACTIVE-IDLE=*AT-DEDICATED-CPUS (see SHOW-VM-RESOURCES INF=*CPU) then the following applies: The idle percentage of these VMs will be output under CPU (%) and not under IDLE.

The HPV CPU (%) ACT and IDLE values are only available on /390 servers.
