Summary of root-cause problems and events

After the initial discovery of the MPLS, VPN, and BGP objects,
continuously monitors the status of the LSP, LdpProtocolEndpoint, RsvpProtocolEndpoint, ForwarderEndpoint, and VRF objects, and the remote ping results, by periodically polling the SNMP agent of the devices in the managed MPLS network. The results of the polling, in addition to the status updates that are received from
IP Availability Manager
and
, serve as input to the
correlation analysis.
detects events from the polling results and from the
IP Availability Manager
and
status updates, and correlates the events to diagnose root-cause problems and to generate impact events. Some of the detected events are misconfiguration events, which are not used to diagnose problems.
creates a problem notification for each diagnosed problem, and creates an event notification for each misconfiguration or impact event.
The
Global Manager
imports:
  • All problem notifications that are diagnosed by
    .
  • All misconfiguration event notifications that are detected by
    .
  • All impact event notifications (described in Chapter 4, “MPLS Cross-Domain Impact Correlation Analysis”) that are generated by
    .
    The root-cause problem notifications and the event notifications are displayed in the
