The CMDB Health Dashboard is a tool that monitors and reports the health of the Configuration Management Database (CMDB) data based on four key performance indicators (KPIs): completeness, compliance, correctness, and relationship accuracy12.
Completeness measures the percentage of configuration items (CIs) that have the required and recommended attributes populated12.
Compliance measures the percentage of CIs that adhere to predefined regulatory requirements, internal governance, and certificates12.
Correctness measures the percentage of CIs that pass the predefined data integrity rules, such as identification rules, orphan CI rules, and stale CI rules12.
Relationship accuracy measures the percentage of CIs that have the expected relationships with other CIs12.
The CMDB Health Dashboard focuses on the first three areas of data quality: completeness, compliance, and correctness12. These areas are also reflected in the overall CMDB health score, which is calculated as the weighted average of the three KPIs12.
The other options, configuration, conciseness, and conformity, are not the areas of data quality that the CMDB Health Dashboard focuses on12.
Configuration is the process of defining and managing the characteristics of CIs, such as their attributes, relationships, dependencies, and status3.
Conciseness is the quality of being clear and brief, without unnecessary words or details4.
Conformity is the quality of being consistent with a set of rules, standards, or expectations5.
