Configuring Hierarchical Correlation Rule Flags

Hierarchical correlation is when a single alarm is both a root cause for one correlation rule and a non-root
cause for another rule, and when alarms are generated resulting in a successful correlation associated with
both rules. What happens to a non-root-cause alarm hinges on the behavior of its correlated root-cause alarm.
There are cases in which you want to control the stateful behavior associated with these hierarchies and to
implement flags, such as reparenting and reissuing of nonbistate alarms. This task explains how to implement
these flags.
See the
about these flags.

Configuring Hierarchical Correlation Rule Flags
Purpose
(Optional) Displays the correlator rules that are defined.
Reissue Nonbistate Flag, on page 8
Purpose
Configures a logging correlation rule.
• Stateful correlations can change specifically if
the root-cause alarm is bistate.
