MIB Collection Data

[Roberto Greco <roberto_greco@IT.IBM.COM>]

   AIX 4.3.2    TME 10 Netview 5.1


  I want to collect data using an Expression.
  From   "Data Collection and Thresholds"  I click on Add button and get
the MIB Object Selection page.
  Here I've the possibility to choose between MIB Object and Expression.
  If I choose Expression I get only three choice but I haven't the
possibility to add one.

  How can I add my own Expression ?

Thanks for your support.
