Missing Operating System Message Appears in Message Queue

Symptom:

I receive one of the following error messages in the message queue during the Reconciliation Engine processing of normalization rules:

• The following discovered operating systems are missing from the Public Operating System list:

  Missing Operating System: operating system name

• The following discovered operating systems are missing from the Operating System list and must be added to the Public Operating System list or the list for tenant: tenant name

  Missing Operating System: operating system name

Note: The Reconciliation Engine writes messages to the message queue in the database. Set the Engine Debug Level in the Hardware Reconciliation Engine Configuration Settings to Fatal (or a higher level of detail) for these error messages to appear in the message queue. For more information about the message queue and the configuration settings, see the CA APM Administration Guide.

Solution:

The normalization rules apply to all tenants and public data and can be used across tenants. If an operating system value assigned through the normalization list does not exist for a tenant, the Reconciliation Engine produces an error message to inform you that the operating system must be added for that tenant or as public data.

Note: For more information about normalization rules, see the CA APM Administration Guide.

If one or two operating systems are missing, you can resolve the problem by adding the operating systems manually to the normalization rules. For information about how to define operating system normalization rules, see the CA APM Administration Guide.

If numerous operating systems are missing, complete the following steps to resolve the problem:

1. Log in to CA APM and click Administration, Reconciliation Management.
2. On the left, click Reconciliation Message Search.

   The message queue displays reconciliation log messages in the Search Results.

3. Search to find the missing operating system normalization rule error messages.

   The message queue displays all missing operating system normalization rule error messages.

4. Verify that the system administrator email address in the product is correct and click Export to CSV.

   The operating systems that are missing are exported to a CSV file. The system administrator receives an email message with a link to the CSV file.

5. Edit the content of the CSV file to prepare the file for the Data Importer. For example, you can remove duplicate operating systems or extraneous words from the file.

   Note: For more information about using the Data Importer, see the Administration Guide.

6. Log in to the CA APM, click Administration, Data Importer, and select the tenant or public data that is missing the operating systems.
7. Import the CSV file.

   The missing operating systems are imported into the CA MDB and are available for use during Reconciliation Engine normalization processing.
