VM report

This report provides monitored data for the individual virtual machines of a VM2000 system.

Report output

The REPORT VM statement is used to request the output of the VM 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 VMs are only output if SM2 is running on the monitor VM. If this is not the case, only the values for the VM on which SM2 is running are output.

Overflow screens may also be requested for this report.

Monitoring information

In the description below, some values refer to the TOTAL TIME. This is the whole available CPU time during the monitoring period.

The following applies: TOTAL TIME = CYCLE * # USABLE CPUS with
CYCLE = duration of the monitoring interval
USABLE CPUS = number of real CPUs, available to BS2000 guest systems (also extra CPUs)

HYPERVISOR
IDLE	Percentage of TOTAL TIME accounted for by IDLE time. IDLE outputs the CPU share which is fundamentally still available. This share is not necessarily available to all VMs.
ACTIVE	Percentage of TOTAL TIME spent by the hypervisor in active time
MEAS %	Percentage of the active time of all BS2000 guest systems in the TOTAL TIME
# USABLE CPUS	Number of real CPUs, available to BS2000 guest systems (also extra CPUs)
IND	Index of the VM
NAME	Name of the VM
VM-GROUP	Name of the VM group the VM belongs to
CPU-POOL	Name of the CPU pool assigned to the VM
I	The monitoring value MEAS contains also the hypervisor idle share of the CPUs available to the VM, if a VM runs in the scheduling mode “Dedicated CPUS” (DC) and uses VM-ACTIVE-IDLE=*AT-DEDICATED-CPUS (see SHOW-VM-RESOURCES INF=*CPU). This is indicated with Y. The VM active share then is only visible in the guest systems CPU report.
MEMORY (MB)	Main memory size of the VM in megabytes
CPU (%)
MAX	Maximum percentage of the VM on the CPU performance. This value relates to all available real CPUs (also extra CPUs). In VM2000 the value can be set with a precision of 0.01%. SM2 only outputs the unrounded, integral part here.
PLAN	Planned percentage of the VM on the CPU performance. In VM2000 the value can be set with a precision of 0.01%. SM2 only outputs the unrounded, integral part here.
MEAS	Percentage of TOTAL TIME that can be accounted for by the CPU time of the VM. VMs which have used no CPU time during the monitoring cycle are not shown. Newly started VMs are not recorded until the subsequent monitoring cycle is completed. If a VM runs in the scheduling mode “Dedicated CPUS” (DC) and uses VM-ACTIVE-IDLE=*AT-DEDICATED-CPUS (see SHOW-VM- RESOURCES INF=*CPU), then the monitoring value MEAS contains also the hypervisor idle share of the CPUs available to the VM. The VM active share then is only visiblie in the guest systems CPU report.
# CPUS	Number of active virtual CPUs assigned to a VM

The connection between CPU MEAS and the CPU values under REAL in the CPU report is explained in detail in section "Special applications".

The HYPERVISOR IDLE and ACTIVE values are only available on /390 servers.
