# Define threshold rules

# Define threshold rules for a test measure definition {#ariaid-title1}

Release version: Brazil  
Updated October 23, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Set the limits for a test measure definition that a captured value is checked against. When a value breaks a limit, the system records a threshold rule violation.

## Before you begin

The test definition must be in the Draft state, and it must have at least one test measure definition. See [Define test measure definitions for a service test](https://www.servicenow.com/docs/RO6uUXF1vhmyTHxa~IRfhg "Define the values that a test captures, such as the metric, the unit, and how often the value is captured.").

Role required: sn_st_mgmt.test_def_creator

## About this task

Each threshold rule belongs to one test measure definition, so you create it from that test measure definition. A rule can compare the captured value against a single exact value, or against a lower limit, an upper limit, or
both.

## Procedure

1. Navigate to AllService Test ManagementTest DefinitionsAll.
2. Select the test definition that you want to open.
3. In the Test Measure Definitions related list, select the test measure definition that you want to define a rule for.
4. In the Threshold Rules related list, select New.
5. On the form, fill in the fields.  
   For the field descriptions and the rules that govern which comparators and targets you can combine, see [Threshold Rule form fields](https://www.servicenow.com/docs/vhMhMGjLB23XT8QqdP9uuw "Review the fields on the Threshold Rule form and the rules that govern which comparators and targets you can combine.").

6. Select Submit.

## What to do next

Define the action to take when the rule is broken. See [Define measure consequences for the threshold rules](https://www.servicenow.com/docs/WJlx6jNvQ7t3eZX95YybtQ "Set actions or responses to trigger when the test measure results fall outside the predefined acceptable limits.").
