Using Port Monitor (portmon.exe) 71
Windows NT
• 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.
