44 Using Port Monitor (rktmon.exe)
Windows 95/98
• View Data: only variables that appear on-screen are included.
The External Program field is used to enter a command line to run
another program after the hourly reports have been generated. For
example, you can use this to run a batch file that performs custom
report processing. The Test button causes the command line to be
executed immediately.
For Day reports, the single and multiple droplists behave the same, but
your choices are:
• None: no report is generated.
• Day Data: only variables with the words “Day” or “Raw” in the
names are included.
• All Data: all variables are included.
• View Data: only the variables that appear in the Port Monitor
window are included.
Likewise, the External Program field is used to enter a command line to
be executed after the daily reports have been generated.
The Update Time option allows you to set the rate at which the port
information is obtained and the calculations performed. There is a
trade-off between Port Monitor efficiency and response time. If you are
using Port Monitor to view the port activity on the screen, you may
want to set the update time to 1 or 2 seconds, so that the screen is
updated frequently. If you are concerned about the monitor program
using CPU resources, set this to a higher value, (6 to 20 seconds) in
order to decrease the time required by the program to perform the
calculations and update the screen.
If Port Monitor is left active to generate reports, minimizing or
reducing the display area of the program will help reduce CPU
requirements of updating the screen.
Port Monitor Files
Port Monitor creates and uses the following files:
• rktmon.vew
• calcs.dat
The default column layout is saved in rktmon.vew. If you have been
experimenting with the appearance of the monitor screen, you can use
the File menu Save option to save your customized layout in another
.vew file. You can retrieve this file later by using the File menu Open
option, or you can use the Edit menu View Default option to retrieve
rktmon.vew and restore the default view.
All Port Monitor calculations are saved at program exit and on the hour
in a binary file named calcs.dat. This enables you to halt Port Monitor
