Configure a MID Server for RCA for business services

To enable the Event Management root cause analysis (RCA) for business services capability, configure at least one dedicated MID Server with the ServiceAnalytics as a supported application, and with the RCA capability. To ensure uninterrupted services, you can configure a failover MID Server cluster for RCA.

Before you begin

If the Domain Support - Domain Extensions Installer plugin is activated, then you can configure a dedicated MID Server with the RCA for business services capability per domain. In this case, RCA for a business service is done on the MID Server that is in the same domain as the business service. Otherwise, a MID Server from the global domain is used.

About this task

The RCA for business services MID Server supports the Event Management RCA for business services process by hosting the RCA Learner and the real-time RCA query handler. On the RCA for business services MID Server, the system builds models that support responses to root cause queries. The learner data on the RCA for business services MID Server persists by default for a maximum of 90 days.

By default, the MID Server is set up as a dedicated MID Server for Event Management RCA for business services, and an attempt to add additional supported applications to the same MID Server is prevented. You should implement Operational Intelligence with its own dedicated Operational Intelligence MID Server. This ensures a high level of performance. However, if needed, you can modify this default behavior and configure the RCA for business services MID Server or the Operational Intelligence MID Server with additional supported applications. For information about modifying the behavior of the ALL option when selecting supported applications, see Select applications to include in the definition of ALL for a MID Server.

Procedure

  1. Ensure that the MID Server is validated.
    For more information, see Validate the MID Server.
  2. Navigate to MID Server > Servers.
  3. Double-click the MID Server that you want to configure as an RCA for business services MID Server.
  4. Add the ServiceAnalytics application:
    1. At the center of the MID Server form, click Supported Applications.
    2. In the Supported Applications section click Edit.
    3. In the slushbucket select ServiceAnalytics and click the > add button.
    4. click Save.
    If the MID Server needs to support ServiceAnalytics as well as one or more other applications, you can modify the definition of the ALL option to include these applications, and then select ALL in the slushbucket. ALL is the only option to which it is valid to add the ServiceAnalytics option. Performance might be compromised with these settings.
  5. Add the RCA capability:
    1. At the center of the MID Server form, click Capabilities.
    2. In the Capabilities section click Edit.
    3. In the slushbucket select RCA and click the '>' add button.
    4. click Save.
  6. Click Update.

Result

The RCA for business services MID Server is automatically configured with a Discovery IP range set to 0.0.0.0-0.0.0.0.

What to do next

Create a failover cluster for RCA. In this cluster, add the MID Servers that were configured for RCA for business services. For more information, see Configure a MID Server cluster.
