Overview
monitors
the status of the discovered session objects by polling the routing-enabled
devices for interface and endpoint status information. The frequency
of polling is determined by the polling and threshold settings that
are configured for , as explained in the .
The
session objects are listed in Session objects and their associated
interface and endpoints objects.

A monitored object is assigned a set of instrumentation objects. | ||

By default, all discovered
session objects are managed. A managed session object is one whose
IsManaged attribute has a value of TRUE. IsManaged is a Boolean attribute:
TRUE when an object is managed, and FALSE when an object is unmanaged.
monitors managed session objects but not unmanaged
session objects. It uses SNMP or CLI to monitor the interface or endpoint
objects that are associated with a session object, for the purpose
of determining the status and connectivity of the session object.
