Print Pega Activity Steps in Logs

Debugging Activities in Pega can sometimes be difficult, especially when:

• Multiple steps are executed
• Activities call other activities
• Parameters change dynamically
• Errors occur intermittently

One of the easiest ways to trace Activity execution is by enabling the internal Activity logger.

This approach allows you to print:

• Activity step execution
• Method calls
• Step transitions
• Runtime processing details

directly into the Pega logs.

---

Use Case

Suppose you want to debug:

• Why an activity is failing
• Which step is executing
• Whether a transition condition is working
• How parameters are flowing

Instead of manually adding logs in every step, you can enable the built-in Activity logger.

Steps to Enable Activity Step Logging

---

Step 1: Open the Activity- Navigate to the Activity rule you want to debug.

Step 2: Open the Activity XML - Inside the Activity rule:- Click on Actions /Select:View XML

Step 3: Search for "Log-Helper"

    Inside the XML, search for: Log-Helper

Step 4: Copy the Logger Name

    Copy the complete logger entry from the XML.

Step 5: Add Logger in Logging Level Settings

• Open Admin Studio
• Navigate to:

    Resources → Logging Level Settings

Step 6: Add the Logger

Add the copied logger name.

Configure:

• Logging Level = ALL
• Duration = 2 Hours

Step 7: Save the Logger Configuration

Save the logger settings.

The logger becomes active immediately.

Step 8: Execute the Activity

Run the activity again from:

• Case processing
• Activity test page
• Flow action
• Job scheduler
• Queue processor

Step 9: Check the Logs

Open:

• PegaRULES log

You will now see detailed activity step execution logs.

Example output:

Activity MyActivity Step 1 Method Obj-Open
Activity MyActivity Step 2 Method Property-Set
Activity MyActivity Step 3 Transition Executed

Benefits of This Approach

Using the Activity logger helps:

• Troubleshoot activity execution
• Identify failing steps
• Debug transition logic
• Trace parameter values
• Understand execution flow

without modifying the activity itself.

Conclusion

Enabling internal Activity loggers is a quick and powerful way to trace Pega Activity execution without modifying existing rules.
