Alert Management Administration › Set Root Cause Analysis Mode

Set Root Cause Analysis Mode

An administrator can set the root cause analysis mode, which determines where root cause analysis is performed. Because CA SOI operators do not have access to the Administration tab on the Dashboard, the administrator should communicate the root cause analysis mode that is set. As a best practice, operators should add the MDR Root Cause and MDR Symptoms columns to the Contents pane, so the operators can easily see if the domain manager is determining the root cause and symptoms. For more information about customizing the Operations Console, see the Administration Guide or the User Guide.

Note: The Domain Manager Derived and Combination modes require that the domain manager and its connector both support sending the root cause analysis information to CA SOI. For current root cause analysis support see the the product-specific Connector Guide that is provided with each connector.

The following root cause analysis modes are available.

CA SOI Derived

A CA SOI derived root cause analysis is performed in CA SOI. CA SOI determines the root cause, symptoms, and the path-of-impact and ignores the domain managers' (such as CA Spectrum) root cause determinations. This method is beneficial when all CIs that are critical to the root cause analysis are modeled in and managed by CA SOI.

Domain Manager Derived

A domain manager derived root cause analysis uses one or more domain managers (such as CA Spectrum) that determine the root cause, symptoms, and the path-of-impact. CA SOI does not perform root cause analysis and uses the domain manager's root cause determination. This method is beneficial in the following example situations:

• The domain manager determines that a CI is the root cause and CA SOI is not managing the CI.
• Multiple domain managers contribute to a CI, but only one domain manager has determined the root cause CI. CA SOI is not managing the CI.
• CA SOI does not have service models that manage CIs that the domain manager reports alerts and root cause analysis on.

Combination (CA SOI and Domain Manager Derived)

A combination of CA SOI and domain manager derived root cause analysis acts as a boolean OR when either CA SOI or a domain manager determines a CI is the root cause. If either CA SOI or the domain manager determines a root cause, CA SOI uses that root cause. The Operations Console may display more than one root cause if CA SOI and the domain manager determine different root causes. If neither a domain manager nor CA SOI determines a root cause, then there is no root cause. The symptoms are determined by either CA SOI or the domain manager. This method is beneficial when CA SOI does not have service models that manage CIs that the domain manager reports alerts on.

Note: Combination mode does not require that all domain managers support root cause analysis.
