These components consist of system properties, scheduled jobs, and tables that drive the calculation, tracking, and reporting of CMDB health KPIs and metrics. Understanding these components helps ServiceNow customers manage performance limits, automate health scoring, and maintain comprehensive health data for their configuration items (CIs). Show full answer Show less ## Properties Installed Several system properties are installed to control processing limits for the CMDB Health Dashboard, allowing you to manage performance when handling large numbers of services and related CIs: * **glide.cmdb.serviceshierarchylimit**: Sets the maximum number of service CIs displayed in the service dashboard hierarchy (default 10,000; range 0-100,000). * **glide.cmdb.servicesquerylimit**: Controls how many application services are processed for the Service View in the dashboard (default 1,000; range 1-10,000). * **glide.cmdb.serviceassociatedciquerylimit**: Limits the number of CIs associated with application services processed in the dashboard (default 1,000; range 1-10,000). These properties reside in the System Properties \[sysproperties\] table and help optimize dashboard performance based on your environment size. ## Scheduled Jobs Installed The plugin installs multiple scheduled jobs that automate calculation and processing of CMDB health KPIs: * Completeness, Compliance, Correctness, and Relationship Score Calculation jobs calculate respective health metrics. * Relationship Compliance Processor evaluates compliance with suggested relationships and hosting/containment rules. * Identifier Field management jobs add or remove recommended fields based on active identification rules to ensure accurate completeness scoring. These scheduled jobs run regularly to keep CMDB health metrics current and actionable. ## Tables Installed Several specialized tables store CMDB Health data, rules, and processing status to support tracking and reporting: * **CMDB Health Metric \[cmdbhealthmetric\]**: Stores settings for KPIs and metrics including enablement and failure thresholds. * **CMDB Health Result \[cmdbhealthresult\]**: Holds results from the latest health processing cycle. * **CMDB Health Scorecard \[cmdbhealthscorecard\]**: Maintains current and historic health scores with status indicators. * **CMDB Health Orphan Rule \[cmdbhealthorphanrule\]**: Defines rules for identifying orphaned records by class. * **CMDB Recommended Fields \[cmdbrecommendedfields\]**: Lists recommended fields per class to guide completeness evaluation. * Internal tables such as **cmdbhealthmetricstatus** and **cmdbhealthprocessorstatus** track KPI processing status and progress. * **CMDB Relationship All Rules Health Results \[cmdbhealthresultrelall\]**: Stores relationship health data for reporting. These tables enable comprehensive health metric management and reporting within your CMDB environment. Several types of components are installed with CMDB Health (included in the com.snc.cmdb plugin), such as tables, properties, and scheduled jobs. Note: The Application Files table lists the components that are installed with this application.
