Adding, editing, or duplicating a user-defined expression
You may want to create an expression to collect information in a specific way. For example, you may

derived from two MIB objects; the MIB object for the incoming packet count and the MIB object for
the outgoing packet count. Take the following steps to add a user-defined expression.
1. Select Monitor > Performance > Expressions
The Expressions dialog box displays.
2. Perform either of the following steps:
• Click Add.
The Add Expressions dialog box displays.
