Create an RCA configuration

Service Analytics uses an RCA configuration to determine which set of alerts from the sa_analytics_alert table to use for RCA. You can create a custom rule-based RCA configuration, compare it with another RCA configuration and decide how efficient and helpful it is. You can then choose the RCA configuration that is most suitable in your environment, and configure RCA to use that configuration in its analysis.

Before you begin

Role required: evt_mgmt_admin

About this task

Each rule-based RCA configuration consists of one or more rules. If an RCA configuration has multiple rules, then the rules' filters are applied to alerts according to their priority order.

If the Domain Support - Domain Extensions Installer plugin is activated, then alerts are processed according to the domain of the associated business service.


  1. Navigate to Service Analytics > RCA Configs
  2. Click New, and fill out the SA RCA SMC Config Base form.

  5. Select the check box for the new rule and click Alert Coverage to calculate the rule's % Alert Coverage.

What to do next

  • Compare the new RCA configuration with another configuration, and decide which configuration is most helpful and should be deployed in the next RCA Learner cycle.
  • After modifying a configuration, or when there is a significant number of new alerts, select any rules and click Alert Coverage. This recalculates the % Alert Coverage for the selected rules.
