Root-cause
problems, exceptions, and events
IP Availability Manager
diagnoses
root-cause problems and detects (computes) events from status changes
gathered from or issued by devices in the managed environment. It
uses the events as symptoms to diagnose root-cause problems.Events used as symptoms to diagnose a failure can also
be perceived as impacts resulting from the failure.
IP Availability Manager
also
generates exceptions, or aggregate events, where an exception is a
collection of problems or events associated with a particular managed
system, IPv6Network, or VLAN. IP Availability Manager
generates an exception whenever any
of the composite problems or events for the system, IPv6Network, or
VLAN occur. For example, IP Availability Manager
will generate an exception for a router
when a card on the router has a problem or the router is down.The
Global Manager
imports all problems diagnosed by IP Availability Manager
and
certain key events detected by IP Availability Manager
. It also imports the IPv6Network inaccessible
exception. The problem notifications (one problem per notification),
notifications (one event per notification), and IPv6Network exception
notifications (one exception per notification) are displayed in the Global Console
.The provides information on key attributes,
diagnosed problems, generated exceptions, and detected events for
all categories of network object types in the
IP Availability Manager
data
model.
