Summary of CMDB Health System Properties
This guide provides essential system properties to configure CMDB Health, enabling effective monitoring and evaluation of Configuration Items (CIs) health. Access to these configurations requires the roles of sncmdbadmin or itiladmin.

Key Features
- Max Running Time: Sets the maximum time (in minutes) for which individual metric processors run in each scheduled cycle. Exceeding this time halts processing until the next job. Default is 120 minutes.
- CI Ownership Field: Defines which attribute in the cmdbci table references User or User Group for ownership determination in Dashboard charts. Default is 'managedbygroup'.
- Logging Level: Controls the level of logging for CMDB Health jobs, aiding in debugging. You can set it to specific levels (e.g., 'error,info') or log all messages using ''. Default is 'error'.
- Audit-Only Results: When enabled, only health results from CMDB Health audits are displayed, excluding data from other sources like Cloud Discovery. Default is false.
- Exclude Dependent CIs: Allows exclusion of dependent CIs from staleness checks, irrespective of defined rules. Default is false.
Key Outcomes
By configuring these properties, ServiceNow customers can customize CMDB Health monitoring processes, enhance logging for troubleshooting, and manage CI ownership visibility effectively. These adjustments lead to improved data accuracy and operational efficiency within the ServiceNow platform.
Configure the following system properties to customize how CMDB Health monitors and evaluates CIs health.
Role required: sn_cmdb_admin or itil_admin
| Property | Description |
|---|---|
Max time in minutes for which individual metric processor will run in each scheduled cycle [glide.cmdb.health.metricProcessor.maxRunningTime] |
If processing of a metric exceeds the specified time, CMDB Health processing halts until the next CMDB Health job is scheduled to run.
For performance reasons, it is recommended not to set this property to a value greater than 120. Note: If you enter an invalid value, the default value is used. |

Attribute in the [cmdb_ci] table that references the User or User Group table. CMDB Health Dashboard charts use this attribute to determine CIs’ ownership. glide.cmdb.health.ci_ownership_field |
Attribute in the [cmdb_ci] table that the CMDB Health Dashboard uses to determine CI ownership.
|
| glide.cmdb.logger.use_syslog.CMDBHealth | A comma-separated list that controls the level of logging of CMDB Health jobs. Logging creates entries in the system logs to capture messages generated by the health auditing process each time they run. This
logging helps debugging if there is a failure. For example, to log error and info messages, set the value to 'error,info'.
|
| glide.cmdb.health.src.cmdb_health_audit_only | When set to true, disables health results from sources other than CMDB Health audit (such as Cloud Discovery). Only results generated by CMDB Health audit appear for KPIs in the CMDB Health Dashboard. For example, by default, if a CI is determined to be stale by Discovery, then that CI is counted as stale for the correctness KPI even though CMDB Health audit didn't determine that CI to be stale. However, in this case, drilling-down the stale CIs metric, still shows those CIs in which source is Cloud Discovery.
|
| glide.cmdb.health.staleness_exclude_dependent_cis | Exclude dependent CIs for the staleness CMDB Health metric. When enabled, dependent CIs are not checked for staleness, regardless of any staleness or inclusion rules that are defined for the respective CI types.
