# Exclude external AI systems from a metric

# Exclude external AI systems from a metric {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Exclude one or more external AI systems from a specific metric, without changing that metric's configuration for every other system.

## Before you begin

Role required: sn_ai_governance.ai_steward

## About this task

You can optionally exclude one or more AI systems from a single metric without affecting other external AI systems. For example, if one agent occasionally handles data that would otherwise fail a secrets detection metric, you can
exclude just that agent from that one metric while still scoring it against everything else.

## Procedure

1. Navigate to AllAI Control TowerHomeSettingsRules and templatesEvaluation.
2. On the AI evaluations sub-tab, select External AI systems.
3. In the Evaluation metrics for Agentic AI section, find the metric that you want to exclude AI systems from.
4. In the Excluded AI systems column, select the pencil icon.
5. In the side panel, search or filter to find the AI systems that you want to exclude.  
   * Fixed filters limit the systems to those that are managed, agentic, and have evaluation enabled.
   * You can find systems where a low score reflects a mismatch with the metric rather than an actual issue by viewing AI systems in the Lowest performing tab.
   * You can find systems that consistently perform well on this metric and don't need continued scrutiny by viewing AI systems in the Highest performing tab.

6. Select the AI systems that you want to exclude.  
   Each selected AI system appears as a removable pill after the list.
7. Select Save.  
   If a selected metric is currently used in a published evaluation template or a compliance evaluation, the exclusion isn't saved, and you're shown which templates or evaluations are using it so you can resolve that first.

## Result

The metric no longer evaluates the AI systems that you excluded. They remain subject to every other metric in your global configuration, and their existing scores for other metrics are unaffected.
