Sun Management Center server activity depends on the following factors:
The number of operations initiated by users
The stability and activity of the host systems under management
The number of management modules loaded by the host systems
The specification of alarm thresholds and rule parameters for properties under management
The last two factors greatly influence the tendency of the managed nodes to generate management activity in the form of event processing.
As a result, high management activity can occur with no add-ons if alarm thresholds are poorly configured. Conversely, low management activity can occur with many add-ons if the managed systems are stable and the alarm thresholds are reasonable.
