Root-cause analysis tasks

Network administrators can perform administrative tasks, such as enabling and disabling RCA, and changing the event maps handled by RCA in order to modify which types of events are handled by RCA. Network operators use RCA to investigate the root cause of events.

Administering RCA

Network administrators can perform various administrative tasks, including the following:
  • Enabling and disabling RCA.
  • Modifying which types of events are handled by RCA by changing the event maps handled by RCA.
  • Changing the relative importance of different event types. When there are multiple events on the same entity, the event with the highest precedence value on the entity is used to suppress other events.
  • Configuring features of RCA behavior, such as the maximum age difference between events that pass through the RCA plug-in. Events that have a difference in age greater than this specified value cannot suppress each other. The default value is 5 minutes.

Investigating root cause

Network operators use RCA to investigate the root cause of events. They can determine which events are root cause and which events are results of that root cause (symptom events) and this enables them to to quickly focus on the events that are causing network problems.
