6.1.1.1 VMS ACCOUNTING Data Collection
To start VMS ACCOUNTING, enter:
SET ACCOUNTING /NEW_FILE /ENABLE=(keywords)
where
NEW_FILE
specifies that the current VMS ACCOUNTING file
should be closed and a new version opened.
'keywords'
are PROCESS and IMAGE. PROCESS is used if
accounting at the process level is desired. IMAGE
is used if accounting at the image level is
desired. PROCESS,IMAGE is specified if both levels
of accounting are desired.
PROCESS accounting writes a PROCESS TERMINATION
record whenever a process terminates. IMAGE
accounting writes an IMAGE TERMINATION record
whenever an image executing within a process
terminates. For example, a process is created for
a user when the user logs on to the system. The
user may then execute editors, compilers, linkers,
system utilities, and previously developed
application programs. In doing so, only one
process has been created.
With PROCESS accounting, when the user logs off, a
single PROCESS TERMINATION record will be created.
With IMAGE accounting enabled, an IMAGE TERMINATION
record will be created at the termination of each
edit, compile, link, utility, or other program
execution. It is clear that IMAGE accounting will
create substantially more records than will PROCESS
accounting. IMAGE accounting is useful when
tracking the resource use of particular program
executions is desired.
Each time the SET ACCOUNTING command is executed, any
current ACCOUNTNG.DAT file is closed and a new one is
started.
A full description of how to start the ACCOUNTING
recording can be found in the VMS Systems Management
Manual.
Sample Procedure:
At midnight, a command procedure is started on each
cluster node that does a SET ACCOUNTING/NEW_FILE that
closes the current file and opens a new version of
ACCOUNTNG.DAT. The procedure then extracts the data from
this file using the VMS Accounting Utility and issues a
file transfer command to pass the extracted version of
the file to MVS for processing in the CA MICS DAILY run.
An alternative is to use the VMS Accounting Utility each
day to extract the previous day's data from
ACCOUNTNG.DAT, if this file is kept as a cumulative file
for a longer time period, such as an entire week or
month.
For example, to extract yesterday's accounting data from
ACCOUNTNG.DAT, issue the command:
ACCOUNTING /BINARY/LOG/NOREJECT/NOSORT -
/OUTPUT=ACyymmdd.dat /SINCE=YESTERDAY /BEFORE=TODAY
See the VMS Accounting Utility Manual for a full
description of how to use VMS Accounting to extract data.
