2.2.1 Data Analysis
The data available in the CA MICS Analyzer Option for VM/CMS
can be used for performance analysis, capacity management,
and accounting and chargeback.
PERFORMANCE ANALYSIS
For VM, performance data is provided by the following
files:
VMXSGP - System Performance data, providing scheduling
information, page rates, simultaneous CHPID busy,
summarized IUCV data, wait states, and CPU busy
VMXSPP - System Performance data at the CPU Level
VMXXDV - Device Activity, providing device utilization
VMXCPV - CP Owned Volume Activity, providing page and spool
activity, and I/O queuing data
VMXVXU - User Activity, providing user resource consumption
VMXCDI - DASD Cache Activity, providing effectiveness of
use measurements for cached DASD
VMXCDP - Paging Cache Activity, providing effectiveness of
use measurements for cached DASD
LNXLXP - Interval view inside of Linux guests, providing
resource consumption, page fault activity, and
memory size for all processes executed.
CAPACITY MANAGEMENT
Capacity data is available in the VMXSGP and VMXXDV files.
The information available includes the following:
o CPU utilization
o Storage utilization
o Logged and active users
o Page and spool slots utilization
o Transaction counts
o I/O rate
o VMDBK waits
o Expanded storage utilization
o Channel path busy
o Device utilization
You can run your own capacity studies using the CA MICS
Analyzer Option for VM/CMS. You can also use the CA MICS
Capacity Planner to analyze VM data. For more information,
see Section 2.2.5.
CONFIGURATION ANALYSIS
System configuration changes can be traced through the
CA MICS Analyzer Option for VM/CMS files.
The following configuration files are available:
VMXSCF - System Configuration File
VMXPCF - Processor Configuration File
VMXDCF - I/O Subsystem Configuration File
VMXACF - CP Owned Volume Configuration File
VMXXSF - Shared System Configuration File
VMXVXF - Logged On Users Configuration File
VMXSCX - Scheduler Parameters File
ACCOUNTING AND CHARGEBACK
Support for accounting and chargeback is provided in five
files:
VMCCMU - Virtual Machine Resource Use File
VMCDAC - Attached Device Use File
VMCVRA - RSCS Use File
VMCNTU - VCNA Network Use File
VMCNDT - Network Data Transmission File
These files provide information about the CPU, spool, and I/O
use of virtual machines, use of attached devices such as
temporary disk and tape, traffic through RSCS, including
destination and file type, and data traffic through VCNA or
VSCS for virtual machines accessing VM using VTAM.
In addition, CA MICS Accounting and Chargeback provides a
complete accounting system for your VM operation. For
further information on the interface for accounting, see
section 2.2.4.
EXCEPTION TRACKING
You can also track exceptional conditions that are reported
in the account or monitor data. The VM Exception File
(VMCVXC) provides this information for all levels of VM
systems. It includes password violations from the journal
data and monitor suspensions.
