    Version history

    Version 18.24.4 - July 2026
    Fix query_range SA on sn_em_tbac_sim_session_alerts.*
    Version 18.24.0 - June 2026
    New: Poactive grouping recommendations are now accessible on the Alert Automation > Group page.Our advanced AI-driven data science model generates these insightful recommendations each month, analyzing alerts to suggest smart grouping automation based on tags. Transforming each recommendation into a rule is a breeze—just a single click with Now Assist lets you review, test, and activate them effortlessly. Dive in and explore this game-changing feature today!
    Version 18.22.0 - May 2026
    Fixed: Fixed performance and scalability issue
    Version 18.20.2 - March 2026
    • New:
      • Two additional grouping criteria have been added to the "Mixed Group" options:
        • Related Log Properties (HLA): This allows you to create grouping automations that combine HLA and Event Management alerts within a single group.
        • Impacted Service Instance: This enables you to adjust the grouping based on your organizational structure.
      • Additionally, a new "Advanced Options" section has been introduced, allowing you to set prerequisite rules for group creation:
        • Minimum Threshold: This option lets you configure a specific number (two or more) of alerts that must match the rule before the group is formed, helping you create more concise and effective groups.
        • Seed Alert: This feature lets you define a filter that requires at least one alert in the group to meet before the group is formed, resulting in more meaningful groupings.
    Version 18.18.3 - December 2025
    New: We’ve upgraded the Mixed Groups option with new grouping capabilities. You can now group by Service Instance, Related Logs Entities (HLA), or both to create precise and effective alert grouping rules.
    Version 18.17.1 - August 2025
    New: You can now create grouping definitions that combine CI relationships and tags, allowing more flexible and accurate alert grouping.
    Version 18.14.0 - May 2025
    No updates.
    Version 18.12.3 - February 2025
    Two minor fixes.
    Version 18.12.1 - November 2024
    • Changed: Group simulation order is now executed in an ascending order
    • Fixed:
      • Fixed time window settings for Tag Based groups
      • Removing unnecessary error message when saving a new Tag Clustering definition
    Version 18.11.2 - October 2024
    Fixed: Groups are not being properly updated when new tags are added to an existing definition.
    Version 18.10.2 - August 2024
    • New: Enable group simulation using the Alert Automation in Service Operations Workspace.
    • Fixed:
      • Fixed upgrade of tag-based clustering definition.
      • Fixed the population of the Assignment Group field.
    Version 18.8.0 - July 2024
    • Fixed:
      • Pattern match happens when source type is one of: additional_info, alert_tags, and cmdb_key_value.
      • Group criteria is working only for alerts with non empty value.
      • ACL for the assignment group field.
      • If a field is selected for group criteria, only alerts with not empty field value are grouped.
    Version 18.7.2 - June 2024
    • New:
      • Tag-Based Alert Clustering Simulation: Helps users test and assess their implementation using simulation mode.
      • Team-Based Rules: Adds the option for team-level rules that are executed only for assigned alerts.
      • Out-of-the-Box Alert Clustering Definitions.
    Version 18.6.0 - March 2024
    • New: 12 new out-of-the-box Tag-based Alert Clustering definitions created.
    • Removed: 4 existing out-of-the-boxTag-based Alert Clustering definitions removed for new customers.
    Version 18.5.3 - August 2023
    Fixed: Fixing issues related to the custom description of Tag-Based groups.
    Version 18.4.8 - May 2023

    New: Clustered alerts are aggregated under a virtual alert rather than one of the real alerts (available starting Vancouver).

    Version 18.3.3 - November 2022
    • New: Supporting alert tags field for alert clustering
    • Fixed:
      • Fixed the link in the blue box message
      • Fixed localization issues

    Fixed: Fixing tags and clustering definitions in a domain separated instance
    Version 18.1.4 - November 2021
    • New:
      • Support tags on CI keys from cmdb_key_value table
      • Support platform patterns on tags to extract values
      • Exclude list property for alert fields
    • Fixed: Bug fixes
    Version 18.0.6 - August 2021
    New: The Tag Based Alert Clustering Engine app is a zero-code method that simplifies alert grouping and performs alert correlation without the need for CMDB, model training, or fine-tuning. The tag-based clustering capability enables alert clustering immediately from activation and works in parallel with existing ServiceNow alert correlation algorithms.
