Summary of Alert insight properties
Alert insight properties allow ServiceNow customers with theevtmgmtadminrole to configure how alert data is retrieved, analyzed, and presented within the Alert Insight pane. These settings manage alert history time frames, similarity criteria, related configuration item (CI) relationships, scoring of relationships, and limits on related tasks. Proper configuration optimizes the relevance and clarity of alert analysis and CI relationships, enhancing incident management and root cause analysis capabilities.

Key Configuration Areas
- Time Frame Settings: Control how far back alert data is retrieved for repeated or similar alerts (default 30 days), and how long recently closed alerts are considered (default 3 days).
- Similarity Criteria: Define which alert fields (e.g., source, type, resource, metricname) determine alert similarity to group related alerts effectively.
- Related CIs Configuration: Determine which CMDB relationship types (containment, hosting, suggested relations) are used to find related CIs and set the maximum depth for application service relationships.
- Scoring of Relationships: Assign scores to different relationship types and levels to quantify the relevance of related CIs. Scores accumulate to prioritize the most pertinent relationships.
- Maximum Related Tasks: Limit the number of related tasks retrieved for alert insights (default 10) to maintain performance and focus.
Metadata Rules and Relationship Management
Alert insight considers parent-child CI relationships modeled via metadata rules, including containment (which CIs contain others) and hosting (which CIs run on others). Customers can manage these rules using the CI Class Manager and Metadata Editor modules, allowing precise control over how CI relationships influence alert insights.
Practical Impact for ServiceNow Customers
- Enables tailored alert grouping and analysis by configuring similarity and related alerts retrieval.
- Improves accuracy of related CI identification by using configurable CMDB relationship rules and scoring.
- Allows customization of alert insight data depth and volume, balancing detail and system performance.
- Supports better incident, change, and problem management by showing relationship affiliations between CIs linked to alerts.
Use these properties to configure alert insight.
The following alert_insight properties are under sys_properties.
| Property | Usage |
|---|---|
| Time Frame | |
| evt_mgmt.alert_insight_alert_history_min | Set the time frame (in minutes) to retrieve repeated and similar alert data.
Default 43200 (30 days) Note: Alerts are retrieved regardless
of their state (open / reopen / flapping / closed). |
| evt_mgmt.alert_insight_closed_alert_window | Set the time frame (in minutes) to retrieve alerts that were already closed. It is the time after the alert last updated date. Default: 4320 (3 days) |
| Similarity | |
| evt_mgmt.alert_insight_alert_same_as_filter | This property is a comma-separated string that defines which of the alert fields is used to consider alerts to be similar. Default: source,type,resource,metric_name |
| Related CIs | |
| evt_mgmt.alert_insight_related_cis_topology_levels The relationship types
are:
|
For ‘Within application service’ relationship type, this property sets the depth or the maximum level of relationship of retrieved CIs. Default: 3 |
| Score | |
| evt_mgmt.alert_insight_group_mapping | This property sets the score for within alert group relations. Default: 2 |
| evt_mgmt.alert_insight_level_1_mapping | This property sets the score for level 1 relationship. Default: 3 |
| evt_mgmt.alert_insight_level_2_mapping | This property sets the score for level 2 relationship. Default: 2 |
| evt_mgmt.alert_insight_level_3_mapping | This property sets the score for level 3 relationship. Default: 1 |
| Maximum related tasks | |
| evt_mgmt.alert_insight_max_tasks | Maximum related tasks to retrieve for alert insight. Default: 10 |
Metadata rules consideration
The parent-child relationship of CIs is considered. Dependent relationship rules consist of hosting and containment rules, each type modeling the data from a different perspective of the CI.
To manage dependent relationship rules:- To access rules at the class level, use the CI Class Manager. Navigate to .
- To access grouped rules, use the Metadata Editor. Navigate to .
Containment rules represent configuration hierarchy of CIs, describing which CI contains which other CIs.
Hosting rules represent placement of CIs in a business definition, describing what CIs run on.
Modify the alert insight properties to configure the way alert information and analysis appears in the Alert Insight pane.
Related CIs configuration
The following properties control which CMDB relationships to consider for related CIs. The CMDB relationships include regular CMDB relation rules, metadata rules (containment rules and hosting rules), and suggested relations.
| Property | Usage |
|---|---|
| evt_mgmt.related_cis_get_all_relation_types | Get all relation types, not including metadata rules. Default: false |
| evt_mgmt.related_cis_use_containment_rules | Use metadata containment rules. Default: true |
| evt_mgmt.related_cis_use_hosting_rules | Use metadata hosting rules. Default: true |
| evt_mgmt.related_cis_use_suggested_relations_rules | Use suggested relations rules. Default: false |
| evt_mgmt.related_cis_validate_relation_rules | This property controls whether to validate relation of CI according to metadata rules. Default: true |
Score
Scores are configured per relation type or depth. Scores are accumulated. The higher the score, the more relevant is the related CI to the current CI.
Example:For a CI that was found at level 2 in the same application service of the current CI, the score is 2. The same CI is in the same alert group, so there is an extra score of 3. The accumulated score is therefore 2+3 = 5.
Affiliation type
The Affiliation Type column in the Related Incidents, Related Change Requests, and Related Problems tabs shows the type of relationship that the CI of the selected alert and the related CI have.
To see affiliation type relationships, navigate to .
The parent-child relationship between configuration items is considered.
