The CA MICS Analyzer Option for VM/CMS uses a variety of
source records to build its information areas:
o The VMC Information Area includes account data from all
levels of VM systems and monitor data from VM systems.
o The VMX Information Area includes monitor data from
VM/ESA and z/VM.
Both information areas maintain system and user measurement
data on service, availability, load, and resource
consumption. In addition, the VMC Information Area includes
exception data (VMCVXC) from all levels of VM systems.
This section defines the use and content of each CA MICS file
in the VMC and VMX information areas.
