Excerpt
Introduction: In traditional SNMP management, problems are detected on an entity either through polling interesting MIB variables, waiting for the entity to send a Notification for a problem, or some combination of the two. This method is somewhat successful, but experience has shown some problems with this approach. Managers monitoring large numbers of entities cannot afford to be polling large numbers of objects on each device. Managers trying to ensure high reliability are unable to accurately determine whether any problems had occurred when they were not monitoring an entity. Finally, it can be time consuming for managers to try to understand the relationships between the various objects they poll, the Notifications they receive and the problems occurring on the entity. Even after detailed analysis they may still be left with an incomplete picture of what problems are occurring. But, it is important for an operator to be able to determine current problems on a system, so they can be fixed.
