Monitoring

Upon importing device topology from
IP Availability Manager
,
performs its own discovery on the devices to gather critical VoIP application information. It models this information as logical topology objects in its repository, and maps the logical topology to the underlying physical transport topology discovered by
IP Availability Manager
.
then monitors the availability of the objects in its repository by monitoring the status of the managed devices and by subscribing to certain device, card, and interface status updates from
IP Availability Manager
. It also monitors the performance of the objects in its repository through status updates received periodically from
.
uses SNMP polling and SNMP trap processing to continuously monitor the status of the objects in its repository:
  • The
    uses a combination of SNMP polling and SNMP trap processing to obtain status update information for the discovered Avaya topology.
  • The
    uses SNMP polling to obtain status update information for the discovered Cisco topology.
  • The
    uses SNMP trap processing to obtain status update information for the discovered Nortel topology.
  • The
    uses SNMP trap processing to obtain status update information from
    .
    The enablement packs apply the status updates to the appropriate attributes of the corresponding topology objects in the
    repository.
