Maintain good quality and health of your application by using troubleshooting tools and techniques that Pega Platform provides. You can view application metrics to locate any issues, and then fix them, so that you deliver top quality application.

• Troubleshooting newly created rules

  If there are issues with copying a rule or data instance, see the following information for troubleshooting help.

• Troubleshooting long-lived clipboard pages

  Clipboard pages that remain unused for long periods could indicate a design or implementation flaw that can hurt performance. For example, the application created a page but neglected to use the Page-Remove method to remove the page after it was no longer needed.

• Finding the class of a rule

  You can view XML data to find the class of a rule. By understanding which class defines a rule, you can more efficiently use tools such as the Application Explorer and Report Editor.

• Application debugging using the Tracer tool

  You can test and debug your applications by using the Tracer tool. You can test and debug activities, data transforms, decision rules, service rules, parse rules, and processes. You can select which rulesets, rules, and events to trace; set breakpoints and watch variables; trace reference properties; select which requestor session to trace; and add custom events to Tracer output. You can also troubleshoot offline-enabled applications in a browser by testing scripts that are running when the application is running.

• Clipboard tool

  Every connected Pega Platform requestor (including browser-based users, even unauthenticated guest users) has an associated temporary memory area on the server known as the clipboard. The clipboard has a hierarchical structure, consisting of nodes known as pages, most of which have a name and an associated class. Pages act as buffers or temporary copies of object instances (of that class) that are copied from, or might later be stored into, the Pega Platform database or another database.

• Log files tool

  In the Log files tool you can view or download the current log files on the server node you are accessing.

• My Alerts display

  You can view the current Alert log on the server node produced by your own requestor session by using the My Alerts display. Select Issues from the Dev Studio developer toolbar.

• Viewing and resolving errors

  Errors appear if you save a form and the system detects one or more errors.

• Viewing in-progress and completed wizards

  You can find all wizards that have been started on the All Wizards landing page. You can use this landing page to clean up incomplete wizards.

• Creating connector simulators

  With the Connect Simulator functionality, test connect rules in flows and from data pages before the actual data source is implemented, or when it is not available.

• The Regular Expression tester tool

  Use the Regular Expression tester to test whether a text pattern matches the regular expression.

• The DateTime parse tester tool

  Use the Date/Time Parse Tester tool to test whether a text input matches the DateTime patterns used by Pega Platform, which are based directly on Java standards.

• About the bulk Revalidate and Save tool

  You can force revalidation in bulk of selected rule or data instances of a single type.

• Application Structure landing page

  The Application Structure landing page helps you to manage and understand the rulesets, rules, access groups, and operators that make up your Pega Platform application. Options on this page display referencing applications, allow you to invite collaborators to the development process, and provides access to other applications on the system (for operators with permission to do so).

• Designing applications for reuse and extension

• Low-code application development
