 ## Summary
 
-This article explains how to use [Live monitor](/power-apps/maker/monitor-overview) with the [Trace function](/power-platform/power-fx/reference/function-trace) to diagnose issues in Power Apps canvas apps. This approach helps you troubleshoot problems that appear only for certain users or in specific environments. Live monitor shows real-time events like network calls, data operations, errors, and performance details. The Trace function lets you add custom diagnostic records to capture values from [behavior formulas](/power-apps/maker/canvas-apps/working-with-formulas#manage-app-behavior) at key moments.

 - Entity counts (rows in collections, related records)
 - Business flags (VIP status, discount eligibility)

 ### Scenario: App works in one environment but not another

+Your app works correctly in *Test* but fails in *Production*. For example, a gallery loads no items and submission is slow. Even though the app is the same, the data in each environment can differ. Missing tables, different column values, larger datasets that trigger delegation limits, or permission differences can cause the app to behave differently.
 
 #### Goal
 
-Surface environment-specific metadata and counts, then compare the sequence and status codes of data operations between environments. In this example, the app has one screen with a form where a **Product** selected from a gallery can be updated. The update works in _Test_ but fails in _Production_.
