Create health inclusion rule

Filter the CIs that are included in health calculations and that appear in the CMDB Health Dashboard by defining health inclusion rules. Use health inclusion rules to temporarily filter out classes that generate a large number of failures, until the problems are fixed.

Evaluation for the required, orphan, recommended, duplicate and staleness health metrics, will apply only to CIs that satisfy health inclusion rules. For example, health inclusion rules can limit CMDB Health scores of the duplicate metric only for server and network CIs.

주:

• You can specify health inclusion rules per domain.
• Creating health inclusion rules at the level of the base cmdb_ci table can potentially filter out health results of all classes in CMDB Health dashboards.
• Applying a health inclusion rule to the duplicate metric, is supported only in the global domain.
• Due to performance issues, dot-walking in health inclusion rules for the duplicate metric is not supported.

In addition to any health inclusion rules, identification inclusion rules also indirectly impact what appears in the CMDB Health Dashboard for duplicate CIs. The dashboard itself uses the identification engine (IRE) to identify duplicate CIs and therefore identification inclusion rules are applied.

Inheritance of health inclusion rules:

• If there are no health inclusion rules specified for a child class, then rules specified on a parent class are applied to the child class.
• If health inclusion rules are specified for a child class, then those rules take precedence over rules specified on a parent class.

In the base system, there are no predefined health inclusion rules, in which case all CIs are included in the CMDB Health calculations.
