This Unix-like facility is provided to help advanced PC users
analyze system activity and to identify programs that are consuming
the majority of system resources.
System activity logging is performed by the SYSACT resident
program. Upon termination of a process, one record is written to
the file C:\SYSACT.LOG. The SARPT batch can summarize this data.

01/25/87 v1.0, Initial release.
02/02/87 v1.1, Added -S option to SAFMT.
Added ACTRPT batch file.
Included ASKYN utility.
02/07/87 v1.2, Included QSORT because DOS sort command will not
sort the activity log when it gets over 64k.
Added -R option to ASKYN and changed ACTRPT to
take advantage of it.
03/07/92 v1.3, Recompiled SAFMT with newer compiler to correct some
problems found when running over a network.

SYSACT - System activity logger
SYSACT.COM (called from AUTOEXEC.BAT)
C:\SYSACT.LOG system activity log file
SYSACT.H log file format definition
SYSACT becomes resident and creates a system activity file, in the
form described in SYSACT.H. This file is interpreted and reported
on by SAFMT.COM and ACTRPT.BAT.
SYSACT should be called once during system startup. This should
normally be done in the AUTOEXEC.BAT file. The activity logger
becomes resident and will remain active until the system is
In multi-process environments, such as DoubleDOS, the activity
logger must be started separately in each partition. Each instance
of SYSACT consumes only about 1k of RAM.
Here is a sample of the contents of the SYSACT.LOG file:
sort.exe 02-01-87 13:28:34 00:00:01.27 0002 0001 0005
turbo.com 02-01-87 13:28:58 00:00:44.21 0003 0000 0010
list.com 02-01-87 13:29:52 00:00:39.99 0006 0000 001B
q.com 02-01-87 13:31:39 00:01:38.92 0001 0001 0016
sort.exe 02-01-87 13:31:56 00:00:10.50 0002 0001 0005
ed.exe 02-01-87 13:43:43 00:08:10.27 0004 0001 0035
The DOS call counters are stored in 16 bits and will overflow to
zero without warning.
SYSACT only reports on processes that have terminated.
ACTRPT PCDOS/MSDOS ACTRPT
ACTRPT - Activity report generator batch
ACTRPT provides a simplified interface to the facilities of SAFMT.
It asks a series of questions and then processes the activity log
based on the operator's responses.
Do you want a standard system activity report? (y/n)
Do you want a system activity report that includes lines for
commands executed only once? (y/n)
Do you want a system activity report without the I/O counts? (y/n)
Output report to the screen? (y/n)
Output report to the printer? (y/n)
Do you want to replace the activity log with a summary
of it's current contents? (y/n)
Here is an example of a report generated by ACTRPT:

SAFMT PCDOS/MSDOS SAFMT
SAFMT - Format command summary from system activity log records
(usually called from ACTRPT.BAT)
SAFMT reads a sorted system activity file, in the form described in
SYSACT.H. It adds all records that executed identically-named
commands and writes them to the standard output.
The options are:
-j Combine all commands invoked only once under ``**others''.
-i Exclude columns containing the I/O counts from the output.
-v Exclude column headings from the output.
-s Produce a compact summary file to replace SYSACT.LOG.
A typical sequence for activity reporting is:
print report1 report2
A typical sequence for activity log maintenance is:
copy c:\sysact.log sysact.old
