 Metric/Param
 Top “N” (1 to maximum configured for that object type) or “Only” one or
more selected objects. For processes, the maximum number of objects is

whereas NonStop nodes can only monitor up to 10. When user clicks on
the “Only” radio button followed by the “Select” button, a new window is
displayed that displays two scopes:
o All available data – List of objects from the trend database for the

data available for them for any selected interval, or as new data is gathered.
 Date / Time to start the display from

always in the top N, so there will be specific intervals in which the entity
