März 2026 * * ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 Minuten Lesedauer Explore different alert grouping types, understand their descriptions, and learn about their creation methods to enhance problem identification and streamline alert management. ## Viewing and managing alert groups {#Alert-Groups__section_whj_npx_3dc} Navigate to Event ManagementAll Alerts to view all alert groups. The icon in the Group column denotes the alert group type, while alerts not associated with any group have no entry in the Group column. Double-click the Group column to open the Grouped Alerts dialog, where you can view all alerts in the group and manually add or remove alerts. Hinweis: An alert can belong to only one alert group at a time. ## Types of alert grouping {#Alert-Groups__section_op1_spx_3dc} {#Alert-Groups__table_xwj_spx_3dc__entry__5} | Type | Icon | Description | Creation method | Additional information | |-|-|-|-|-| | Log Analytics | L | Log Analytics groups are formed when the system identifies multiple related Log Analytics alerts, grouping them based on their significant connections. | Created as part of log analytics event processing. | [Kinds of Health Log Analytics alerts](https://servicenow-prod.fluidtopics.net/wyhSBPwW96jRO1m_dsi4BQ "Health Log Analytics generates several types of alerts.") | | Rule-based | R | Rule-based groups consist of related alerts that are organized based on compliance with alert correlation rules, which determine how alerts are grouped according to their relationships. | Created via business rule (Calculate correlation rule) on em_alert table when alert is created or updated. | * [Rule-based alert grouping](https://servicenow-prod.fluidtopics.net/Ro~MrJwQNzpzGj2DvnbAKA "Rule-based alert grouping is created by alert correlation rules. These rules allow you to manually classify alerts as primary or secondary and establish a relationship between them. Use alert correlation rules to group related alerts. The rule runs only for new alerts or alerts whose status changed from close/flapping to open/reopen.") * [Create an alert correlation rule](https://servicenow-prod.fluidtopics.net/adOib_SN6QkVyk9TXrp97A "Create an alert correlation rule to designate primary and secondary alerts. The primary alert is identified as the root cause of the alert group and the secondary alerts are grouped under the primary alert.") {#Alert-Groups__ul_b1y_vzg_qfc} | | Automated | A | Automated groups are formed by alert aggregation and include a virtual alert as the primary alert of the group. An Aggregated automated group is created when two or more alerts share the same CI type and metric name. | Created via scheduled job. | [Automated alert grouping](https://servicenow-prod.fluidtopics.net/2kPgZstYZaOZmmU3pILJQw "Automated alert grouping is a process that uses historical data to automatically organize similar alerts into groups. These alerts could be system issues, like server errors or network outages. By grouping related alerts together, it helps teams quickly identify patterns, manage recurring problems, and reduce the noise from too many individual alerts.") | | CMDB | C | CMDB groups are formed based on CI relationships in the CMDB, specifically for CIs that are not included in rule-based or automated groups. | Created via scheduled job. | [CMDB based alert grouping](https://servicenow-prod.fluidtopics.net/vFiGCDb~l~c7EL995kcJHA "CMDB based alert grouping helps organizations manage alerts by organizing them according to their related configuration items (CIs) within the Configuration Management Database (CMDB). This method group alerts based on CI relations in applications or infrastructure components, allowing teams to better understand the impact of issues, respond more effectively to alerts, and maintain service availability.") | | Network traffic based | N | Network traffic alert groups are formed by analyzing network traffic connections between processes across hosts. This method leverages service candidates identified through ML Service Mapping to group alerts related to network traffic issues. | Created via scheduled job. | [Network traffic based alert grouping](https://servicenow-prod.fluidtopics.net/QC1V7QKMocU2j9KHjKBozQ "The Network traffic based alert grouping method groups alerts by analyzing network traffic connections between processes across hosts. It leverages service candidates identified by ML Service Mapping to group alerts related to network traffic issues. This ensures alerts from directly connected processes within the same service candidate are grouped together, offering a more contextual view of network incidents.") | | Text | T | Text groups are formed by grouping alerts based on similar text from frequently used words in following fields. * Description * Metric Name * CI Class {#Alert-Groups__ul_ywj_spx_3dc} | Created via scheduled job. | [Text-based alert grouping](https://servicenow-prod.fluidtopics.net/tJvWHA8_DEHUH3o744yHmQ "In text-based alert grouping, alerts are organized and correlated based on specific text patterns or keywords within the alert content. This approach dynamically groups alerts that share similar textual characteristics, such as error messages or event descriptions, allowing for more flexible and adaptive management of alerts.") | | Tag Cluster | Tag | Tag Cluster groups are formed by grouping alerts according to user-defined tag-based alert clustering definitions. | Created via scheduled job. | [Tag cluster alert grouping](https://servicenow-prod.fluidtopics.net/CiExAcdq66gzLWgMaapbJw "Tag cluster alert grouping enables you to easily create groups of alerts. It is a non-code method of alert grouping that correlates alerts without having to use CMDB or model training. This simpler way of grouping similar alerts reduces the overall noise of a large quantity of alerts.") | | Manual | M | Alerts grouped manually by users to organize related issues. | Created manually by the user. | [Manual alert grouping](https://servicenow-prod.fluidtopics.net/y9ib8dFFr0MqK1JmyEiVnA "Manually create an alert group to organize and manage related alerts when not using scheduled jobs. This provides flexibility to group alerts on-demand for effective resolution.") | [Tabelle : 1. Alert grouping types] {#Alert-Groups__table_xwj_spx_3dc} For information on scheduled jobs and parameters, refer to [Scheduled jobs and parameters for alert grouping](https://servicenow-prod.fluidtopics.net/zzJmJVUfgrMofThfR5Rtgw "Automate alert organization by configuring jobs to group alerts based on predefined criteria and parameters.").

This feature empowers you to fine-tune correlation methods to their specific needs, enhancing alert prioritization and response efficiency.").
