New features

Between your current release family and Yokohama, new features were introduced for Event Management.


Release	Release notes
Vancouver	Container alert for tag-based groups Enhance alert group creation using tag-based alert clustering. The primary alert of a tag-based group is a container of child alerts that meet the Tag-Based Clustering definition. Event Management Connectors domain personalization Enhance domain separation to be able to create events in different domains with configurable domain separation logic for events. Agent assist Enhance the user experience by adding the Agent Assist panel to alerts in the Service Operations workspace. Create event field mappings Provide more comprehensive information in an alert by mapping values from the reference table to the alert fields or tags.
Washington DC	Team-based integrations in Event Management Ensure connector ownership and execution of rules on a team level, maintaining consistency and hierarchy while offering flexibility and customization options for teams. Automate the assignment of alerts based on integration ownership and configuration item (CI) ownership so alerts are routed to the appropriate team members responsible for the integrated systems. Event forwarding Forward events from one ServiceNow instance to other instances in non-production environments without having to change the production environment, thus accelerating the event processing testing life cycle. Free-text search for alerts in Express List Starting in version 23.2.1, find alerts in the Express List by using free-text search. Keyboard shortcuts in Express List Starting in version 23.2.1, speed up your work in Express List with keyboard shortcuts. Timeline View of alerts in an alert group in Express List Starting in version 23.2.1, use Timeline View in Express List for a chronological visualization of the alerts in an alert group. This feature offers a comprehensive view of when the alerts occurred, when changes in their severity took place, and other data for efficient triage and Mean Time to Resolution (MTTR). Link View in Express List Starting in version 23.2.1, view the connections between alerts in rules-based or CMDB-based alert groups in Link View. Link View offers a visual representation of the relationships between the alerts in the group. Alert analysis of alert groups in Express List created by Now Assist using generative AI Starting in version 23.2.1, view an alert analysis of alert groups in Express List. The alert group analysis provides a simplified, human-readable description of the alerts in an alert group to help you investigate the alerts.
Xanadu	Customize the default order of the alert correlation algorithm Configure the alert correlation algorithm sequence by customizing it according to your needs. Create team-based alert management rules Assign alert management rules to specific assignment groups so that only those alerts that are assigned to the specified group are executed. Create tag based alert clustering definitions by teams Create tag clusters only for alerts that are assigned to an alert group by assigning tag-based alert clusters to specific groups. Restrict alert groups across alert assignment groups Improve the accuracy and relevance of the alert correlation by grouping alerts according to a diverse set of requirements. Scale out for alert group creation Ensure efficiency when running a job during high-alert traffic by scaling out the alert grouping job. View unified service map and the impact paths in Service Operations Workspace Explore the updated service map in the Service Operations Workspace, designed to focus on the path that was affected by an alert to help you quickly assess its impact on a service. The map displays all configuration items (CIs) for services with up to 60 CIs, regardless of alert status. For services with over 60 CIs that have alerts, it shows the path of the most severe, most recent alert. You can also investigate an even broader view of the service topology. Access the service map directly from Service Operations Workspace, or through the preview panel or an impacted service in Express List. Perform bulk actions on alerts in Express List Perform an action on up to 1,000 alerts in the Active alerts list simultaneously. Remove alerts from an alerts group in Express List Remove secondary alerts from an alert group directly from the Express List pane or from the preview panel. Hide closed alerts on the preview panel and in Link View in Express List View only the open alerts on the preview panel and in Link View in Express List by toggling to hide the closed alerts. View data on impacted services on the preview panel in Express List View information about Impacted Services on the preview panel and in Link View in Express List and open the Service Map and Metric Explorer directly from the panel. Create an incident with Now Assist in Express List Generate incidents from alerts in Express List with a summary created by genAI that includes details on configuration items and impacted services. View data on configuration items on the preview panel in Express List View additional details about configuration items (CIs) that are bound to alerts on the Express List preview panel. Speed up alert resolution with a Now Assist analysis of past related incidents Enhance efficiency and reduce downtime with a Now Assist analysis of past incidents on the same or related CIs. Now Assist investigates historical data to identify past incidents related to the current alert and reports their frequency and criticality levels. It also provides a summary of effective strategies used to resolve them. In addition, Now Assist offers contact information for individuals or teams who have resolved similar incidents in the past and could assist when needed. Generate an alert group description in Express List using Now Assist Use Now Assist to generate a description of an alert group in Express List that encompasses all the alerts within the group. The generated description replaces the original description of the group. Launch an alert analysis from the Now Assist panel Analyze an alert from the Now Assist panel. The alert analysis displays directly in the Now Assist panel for convenient review.
Yokohama	Group alerts using network traffic-based grouping Group alerts efficiently with network traffic-based alert grouping, which uses discovered TCP connections with ML Service Mapping to correlate alerts on host CIs that have network traffic connections between them. View links between alerts in network traffic-based alert groups Once a network traffic correlation is enabled, investigate network traffic alert group details and visualize connections through Link View in Express List®. New role for team level operators Enhance team-level control over alert management with the evt_team_operator role. This role enables operators to manage Event Management operations within their assigned team, including reading and writing alerts, making configuration changes,updating Alert Automation, and setting up new integrations in the Integrations Launchpad. [Placeholder link text to key esc-notify-alert-sow-itom] Starting in version 26.7.0, execute response subflows automatically, manually, or both for alerts that match specific conditions through the Run Other Response Actions option of Respond Automatic. This enhancement offers better control over automated responses with configurable execution limits and multiple response actions. [Placeholder link text to key enrich-alert-sow-itom] Starting in version 26.7.0, link a CI to an alert for more accurate IT component mapping though the Improve Configuration Item (CI identification option of Enrich Automation. This enhancement improves alert visibility, speeds up issue resolution, and ensures better correlation between alerts and infrastructure components.
