This general capability does not exist without instrumenting each activity.

However, if you are on Pega 7.1.7 or above you can use the Rule Collection rule type to execute your activities.  Collections (7.1.7+) have the ability to "know" about the pzinskey of the rules it executes during the response action (from here you can execute any functionality you need).

Hi,

Use the following Java code in each activity without a step page to get Activity name and class name. You can get Ruleset and Version by passing these values as parameters to some rule resolution activity.

String javaClassname = "";
StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();

int j = 0;
for (int i = 0; i < stacktrace.length; i++) {

 if (stacktrace[i].getMethodName() == "perform") {
  j++;
 }
 if (j == 1) {
  javaClassname = stacktrace[i].getClassName();
  break;
 }
 //oLog.infoForced("classname : "+stacktrace[i].getClassName() + " and method name : "+stacktrace[i].getMethodName() );
}
int startIndex = javaClassname.indexOf("_action_") + 8;
int endIndex = javaClassname.lastIndexOf("_");
String actName = javaClassname.substring(startIndex, endIndex);
//oLog.infoForced("Activity Name: "+actName);
tools.putParamValue("CallingActName", actName);

//ClipboardProperty  ThisClass= myStepPage.getProperty("pxObjClass");
String ThisClass = myStepPage.getString("pxObjClass");
oLog.infoForced("Class: "+ThisClass+" | Activity Name: "+actName);
