When you run a stand-alone inventory package, the package uses the options that you specified when you created the package. When you run a package, you can use command-line switches to modify default behavior.
By default, all the errors are logged. If you specify /EnableVerboseLog at the command line, it enables verbose logging. If verbose logging is enabled, the trace messages are also logged.
The log is stored on the local computers at the following locations:
On managed computers, in InstallDir\Altiris\Altiris Agent\Logs folder, as Agent*.log
On unmanaged computers, in %ProgramFiles%\Altiris\Altiris Agent\Logs folder, as a*.log.
By default, a stand-alone inventory package reports all the gathered inventory data. If you use this switch, the package reports only the inventory data that has changed since the last scan.
To gather only changed data, the package compares the gathered inventory data to the previously collected data, if the previous data was cached. To cache inventory data, check Keep the inventory cached for future comparisons in the package configuration page.
