Network Monitor gives you the ability to automatically start capturing network information upon starting the program. This is completed by using command-line parameters that can be passed to the program.


You can use this feature, for example, in conjunction with the AT command to start Network Monitor when a backup operation begins. To do this, put the command to AUTOSTART Network Monitor in the batch file just before the backup operation starts, as in the following example batch file:
@echo off
Start Netmon /AUTOSTART
NTBACKUP backup C:\<directory path> /B /L "C:\BACKUP.LOG"
The rest of this article describes the command line options for running Network Monitor. For more information, see the Network Monitor Help file in the Systems Management Server Administrator's Guide.
