task australia Updated Oct 23, 2026 1 min read define-threshold-rules.md

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.

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

Navigate to All > Service Test Management > Test Definitions > All.
Select the test definition that you want to open.
In the Test Measure Definitions related list, select the test measure definition that you want to define a rule for.
In the Threshold Rules related list, select New.
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.
1. Select Submit.

What to do next

Define the action to take when the rule is broken. See Define measure consequences for the threshold rules.
