Diagnostics

Run diagnostics on Decision Center through the Business console to get metrics on your projects and decision services.

As an administrator user, you can run diagnostics on different parts of Decision Center. Get information about versioning, data sources, extensions, verbalizers, and databases.

Diagnostics for artifact counts and projects give you information about how many artifacts you have and their types, and the organization of your decision services. This service gives you precise metrics about your projects and decision services. The results of the diagnostics can also be found in your server logs, or downloaded in a JSON file.

Diagnostics can be used to check your database schema to determine whether it is compatible with your installed version of Decision Center. The results can tell you when to upgrade:

  • Schema version error: Migrate your schema to the latest version if the diagnostic is red. Although this schema is supported, it is not the best version for this release of the product.
  • Schema modification: Apply the schema addition by using the update script when available to ensure the best performance of your Decision Center.
    Note: Shut down Decision Center before running the update script. This prevents concurrency issues while running the script, and you must restart Decision Center to load the updates.

To access this service, open Administration > Diagnostics in the Business console. The Diagnostics tab can include the following tests:

  • About: Provides system information, including the version.
  • Artifacts Counts: Counts the artifacts and categorizes them by type.
  • Artifacts Counts per decision service: Counts the artifacts for individual decision services.
  • Billable Artifact Counts: The artifacts for which you are billed.
  • Billable Artifact Counts per decision service: The artifacts in individual decision services for which you are billed.
  • Project: Shows the number and types of projects.

The Artifacts Counts per decision service diagnostic (either billable or not) provides the number of artifacts that are created for each decision service. Because the decision services can share common artifacts through shared projects, these artifacts might be counted in different decision services. Also, this diagnostic does not count elements that belong to projects that are not used by a decision service.

Billable Artifact Counts

For customers on subscription services, you can display the artifacts for which you are billed in a section called Billable Artifact Counts. You can track project usage, and charge subscription costs to specific business units.

The Billable Artifact Counts section is not shown by default. In the preferences.properties file, set the following preference to true to display the section in the Diagnostics subtab of the Administration tab: decisioncenter.com.ibm.rules.metering.billableCount.enable.

The billable count filters out artifacts that are deleted and no longer in any snapshot or branch. For example, the billable count does not take into account an element created and then deleted immediately. However, if the element is referenced by a new branch before the element is deleted, it is still taken into account because it can be managed in the new branch even though it has been deleted from the original branch.
