- I have tried many usage logging systems, and have found that they all seem to
- fall short. The NLOG system is my attempt to address the problems I have
- encountered which are:
-
- * Some of my youg operators like to enter garbage into the database
-
- * Collecting log-in time is easy, collecting log-outs is hard because
- operators can just turn the computer off.
-
- * During program development, one can end up booting many times, and
- I wanted to get through log-in ASAP.
-
- * Everybody has their own needs, so I wanted to have something that
- was easy to customize, but needed no special language processors
-
- The NLOG system is written in the DOS .BAT language with a few extensions that
- are included in this .ARC file. To install it, you will need to tailor it
- some, as this is operational code from my system, and it will take some changes
- to meet your needs.
-
- Installation:
-
- I. Modifying the NLOG.BAT file:
-
- Near the top of the file is the file location customization section.
- logdir The full name of the directory is where the log files are
- kept.
-
- progdir The full name of the directory where the log programs SETNOW
- and SETREAD are found.
-
- rem Customization section start:
- set logdir=c:\$temp
- set progdir=c:\utility\
- rem Customization section end:
-
- Further down is a section where the initials of authorized users of
- the system are validated. The initials of the users are the
- capitalized JSK, DLK, ... etc, below. The z is appended to avoid
- syntax errors if a user replies with just a carriage return.
- Alter this portion of the .BAT file as required by your situation.
-
- :getwho
- echo Enter your initials, then ─┘
- %progdir%setread who /u
- if z%who% == zJSK goto gotwho
- if z%who% == zDLK goto gotwho
- if z%who% == zSAK goto gotwho
- if z%who% == zSLK goto gotwho
- if z%who% == zABK goto gotwho
- echo Only Krueger household initials are accepted, not %who%!!!
- goto getwho
-
- :gotwho
- if %who% == JSK set username=Joe
- if %who% == DLK set username=Dan
- if %who% == SAK set username=Sarah
- if %who% == SLK set username=Sue
- if %who% == ABK set username=Arny
- echo %username%, please type Business or Pleasure (B or P)
-
-
-
- II. Modifying your AUTOEXEC.BAT file:
-
-
- rem login the usage:
- set progdir=c:\utility\
- %comspec% /e:640 /c=c:\utility\nlog
-
- The set line duplicates the line you updated in NLOG. In this
- application, it controls checkpointing (see below).
-
- This %COMSPEC% line is appropriate for DOS 3.2. For DOS 3.1 modify the
- /e parameter by dividing by 16. In the example this means changing
- the 640 to 40.
-
- III. Modifying your CONFIG.SYS file:
-
- The NLOG batch file will add some variables to the environment.
- It is recommended that you extend the size of the environment as
- follows:
-
- SHELL=C:\command.com /p /e:640
-
- Again, this is a DOS 3.2 version. For DOS 3.1 change the 640 to 40
- since DOS 3.1 sizes the environment in paragraphs. DOS 3.2 sizes
- the environment in bytes.
-
- IV. Checkpointing. A key concept of this system is that checkpoints
- are taken as people use various .BAT files on your system.
- The checkpoint then contains a fair estimate of the last time of
- use of your computer. If the user logs out explicitly, then the
- checkpoint file is deleted. If he does not, the next time he
- attempts login, he will be prompted to close the previous session.
- He can do this three ways:
-
- 1. Continue the previous session.
- 2. Logout the previous session using checkpoint data
- 3. Logout by typing in new time/date information.
-
-
- The following code should be copied all over the .BAT files on your
- system to ensure the checkpoint files are kept up to date:
-
- c:\utility\setnow
- c:\utility\setdir autdir
- cd %logdir%
- echo %date% %time% C checkpoint >newlog.log
- cd %autdir%
- set autdir=
