How are Completeness, Correctness and Compliance set up in CMDB Health?

I'm looking for some clarification and best practices on how the completeness, correctness and compliance metrics in the CMDB Health Dashboard are defined and configured

• Completeness:

  This refers to whether all the necessary and required data is present for each Configuration Item (CI) in the CMDB. It ensures that critical information is not missing.

  • Example: A server CI should have details like its operating system, hardware specifications, and associated applications. If any of these are missing, the CI is considered incomplete.
• Correctness:

  This focuses on the accuracy and validity of the data within the CMDB. It ensures that the information is up-to-date and free from errors or inconsistencies.

  • Example: A server's IP address in the CMDB should match its actual IP address. If they don't match, the CI is considered incorrect.
• Compliance:

  This refers to whether the CIs in the CMDB adhere to established standards and configurations. It ensures that the CMDB reflects the desired state of the IT environment.

  • Example: If there's a policy that all servers must have a specific security patch installed, the Compliance metric would verify if the CIs representing those servers show that patch as installed.
