Configure a dedicated MID Server for Service Analytics

To activate root cause analysis (RCA) with Service Analytics, configure at least one dedicated MID Server with analytics. To ensure uninterrupted services, it is recommended that you also configure a failover MID Server cluster for analytics.

Before you begin

If the Domain Support - Domain Extensions Installer plugin is activated, then you can configure a dedicated MID Server with analytics, 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 analytics MID Server supports the RCA process by hosting the RCA Learner and the real-time RCA query handler. On the analytics MID Server, the system builds models that support responses to root cause queries. The learner data on the analytics MID Server persists by default for a maximum of 90 days.

The MID Server must be dedicated for Service Analytics, and an attempt to use it for Discovery for example, is prevented.

Procedure

  1. Ensure that the MID Server is validated.
    For more information, see Validate a MID Server.
  2. Navigate to MID Server > Capabilities, and click Analytics.
  3. Select the MID Server that you want to configure analytics on.
    1. In the MID Servers section, click Edit.
    2. On the Edit Members form, select the MID Server and move it to the Analytics list.
    3. Click Save.
  4. Click Update.

Result

The Analytics 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 analytics. In this cluster, add the MID Servers that were configured for analytics. For more information, see Configure a MID Server cluster.
