1.3 Files Overview

The CA MICS VAX/VMS Analyzer builds the VAX/VMS Monitor
Information Area, the VAX/VMS Accounting Information Area,
and the VAX/VMS System Usage Information Area.  Once created,
these Information Areas maintain system and user workload and
utilization data.  This section defines the use and content
of each file from the CA MICS VAX/VMS Analyzer information
areas.



VAX/VMS ACCOUNTING FILES

The VAX/VMS Accounting Information Area maintains system and
user utilization data for accounting and chargeback.

volumes mounted.  It is derived from the VMS ACCOUNTING type
3 record.

This file maintains information on system initializations.
It is derived from the VMS ACCOUNTING type 5 record.

This file maintains information on unsuccessful attempts to
gain access to the system.  It is derived from the VMS
ACCOUNTING type 7 record.

This file maintains information on printing, including start
time, queue time, pages printed, and I/O count.  It is
derived from the VMS ACCOUNTING type 8 record.

o Process Termination (DEAPRC) file

This file maintains information on processes terminated,
including starting time, CPU time, page faults, fault I/O,
direct and buffered I/O, maximum working set size, and
volumes mounted.  It is derived from the VMS ACCOUNTING type
1 record.

The VAX/VMS Monitor Information Area maintains system
workload and response data for monitoring system
performance.

o Disk (DEMDSK) file

This file maintains information on VMS disk activity by
volume, including number of I/O operations and queue
lengths.  It is derived from the VMS MONITOR type 12 record.

o Modes (DEMMOD) file

This file maintains information describing the time spent in
each of the processor modes:  interrupt, synchronization,
kernel, executive, supervisor, user, compatibility, and
idle.  It is derived from the VMS MONITOR type 2 record.

Also, CPU time of Vector Consumers is provided from the VMS
MONITOR type 23 record.

o Process (DEMPRO) file

This file maintains information on the processes executing in
the system:  process name, page count, I/Os, and CPU time.
It is derived from the VMS MONITOR type 0 record.

o RMS (DEMRMS) file

This file maintains information on the VMS Record Management
Services (RMS), including, among others, GET bytes, PUT
bytes, update bytes, deletes, finds, connects, and
disconnects.  It is derived from the VMS MONITOR type 20
record.

o SCS (DEMSCS) file

This file maintains information on the VMS System
Communication Services (SCS) activity, including datagrams
sent, received, and discarded; send-datas; messages sent and
received; and kilobytes transferred.  It is derived from the
VMS MONITOR type 15 record.

o System Profile (DEMSPR) file

This file maintains consolidated information on many aspects
of system operation.  It is derived from the VMS MONITOR
class records for system class, including type 1, 3, 4, 5, 6,
7, 8, 11, 14, 17, 19, 21, and 22 records.

Specific types of information in this file:

  - Overall system operation, including CPU busy, read I/Os,
    direct I/Os, buffered I/Os, free page count, modified
    page count, and number of active processes.

  - Cluster-wide VMS lock activity, including enqueues,
    dequeues, and conversions.

  - DECnet activity, including arriving and departing
    packets, lost packets, and buffer failures.

  - Distributed Lock Management Facility, including enqueues,
    dequeues, and conversions.

  - VMS file system ancillary control processes (ACPs),
    including new files, page faults, and read and write
    I/Os.

  - VMS File System Cache, including cache attempts and hits
    for directories, file headers, file IDs, and extents.

  - VMS I/O subsystem, including direct I/Os, buffered I/Os,
    page reads, page writes, and page faults.

  - Lock management in VMS, including enqueues, dequeues, and
    deadlocks.

  - MSCP server activities, including reads, writes,
    requests, and I/Os of various sizes.

  - VMS Page Management System, including page faults, reads,
    read I/Os, writes, write I/Os, faults, and free pages.

  - VMS space allocation in the nonpaged dynamic pool,
    including packets free and in use (small, intermediate,
    and large), kilobytes free and in use, and largest and
    smallest blocks available.

  - Number of processes in each scheduler state:  waiting,
    hibernating, suspended, inswapped, and outswapped.

  - Transaction processing statistics for DECdtm services,
    including transaction starts, commits, aborts and ends.



VAX/VMS SYSTEM USAGE FILES

The VAX/VMS System Usage Information Area maintains disk
usage data by user for accounting and chargeback, disk quota
and disk device information for managing overall storage use,
process activity information based on combined Monitor and
Accounting data for an enhanced view of Monitor data on
performance by workload, and other useful information on
system status.

o Disk Device (DESDKD) file

This file identifies device type, volume name, and volume set
membership for each active disk device on each VMS system,
and includes readings of device free blocks, device total
blocks, and most recent error count.  The source of this file
is the VMS ANALYZE/DISK_STRUCTURE Utility type 01 record and
the VMS SHOW DEVICE output.

o Disk Quota (DESDKQ) file

This file quantifies disk usage by disk device and
Diskquota-displayed User ID Codes (UIC's).  Measures include
quota usage, permanent quota, overdraft limit, and
megabyte-hours of quota usage storage.  The source of this
file is the VMS SYSMAN Utility, DISKQUOTA SHOW output.

o Disk Usage (DESDKU) file

This file quantifies disk usage by account code levels, plus
directory top level at the DAYS time-span, and individual VMS
directories and files at the DETAIL time-span.  Measures
include blocks allocated, blocks used, and megabyte-hours of
storage.  The source of this file is the VMS
ANALYZE/DISK_STRUCTURE Utility type 02 record.

o Process Activity (DESPRX) file

This file quantifies the resource usage of each process on
the VMS system during the monitoring interval, by user ID
code (UIC), username, VMS account name, terminal name, and
process type and name.  The source of this file is the VMS
ACCOUNTING Process Termination record, type 01, and the VMS
MONITOR Processes record, type 00.

o System Status (DESSYU) file

This file provides a variety of system readings for each
execution of the CA MICS DEXSUS collection routine, including
system hardware name, system uptime, VMS version, number of
CPU's, main memory, and many other system settings.  The
source of this file is the VMS MONITOR System Information
record, type 129, VMS SHOW SYSTEM and SHOW MEMORY output, and
several VMS lexical functions, including F$GETSYI.
