Using Port Monitor 39
Port Monitor Files
Port Monitor creates and uses the following files:
• portmon.vew
• calcs.dat
The default column layout is saved in portmon.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 portmon.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 execution without losing accumulated data.
Port Monitor also creates a \REPORTS directory. All hourly and daily reports are saved in this directory,
under the following names:
• hall.txt — hourly single report
• dall.txt — daily single report
• hcomx.txt — hourly multiple reports, where x is the port number
• dcomx.txt — daily multiple reports, where x is the port number
Caution: Since multiple reports append new data each time they are written, the multiple report files grow in
size. It is up to you to delete them periodically.
Some safeguards are built into the program to avoid filling up a hard disk drive due to growing report files.
The monitoring program stops writing additional data to the multiple reports if they reach a size of 2 MB.
Also, the program will not write out data files to the disk drive if the spare room on the drive is less than 2
MB in size.
To view or edit an hourly or daily report, use the Edit Report option on the File menu, or use a system tool
such as NOTEPAD.
For more information, see the Port Monitor Help file.
