This documentation supports the 20.08 version of BMC Discovery.

To view an earlier version of the product, select the version from the Product version menu.


The tw_top utility provides a filter on the top utility which enables you to view just BMC Discovery processes. The top utility displays and updates a list of processes, ordered by default by CPU usage. You can use other sorting and display criteria. For more information see the top documentation, man page, or when the utility is running press ? to display help.


The process and service command lines are long so it works best with a wider terminal window.

Options in the utility specify which processes and services to display. To use the utility, type the following command:

tw_top [options]
