System Notification of Errors
Performance Management provides information for errors that can prevent the
system from performing its task. Errors can display in the following ways:
• Pop-up error messages
• Alerts shown in the left pane
Error and
Exception Log
All performance exceptions and selected errors are recorded in the database in
an event log. You can view the events by viewing the various event log panes,
which generate alerts that have an associated severity level based on how the
alerting parameters are defined. The alerts appear in the left pane and are
associated with the DEFINITY component (managed node or performance report)
that generated the event.
SNMP problems generate a data collection failure event. A scheduled report that
is not generated also generates an event. Exception events are performance
exceptions that are outside threshold limits as defined for the system.
Performance Management periodically checks the event log and deletes records
whose start time exceeds the defined time that event records are kept.
