How do I capture the messages on the fly in IIB?

IBM has provided lot of ways to capture the messages flowing through our message flows. In this post, we are going to discuss about one of them and it is also one of the most unnoticed.

IIB allows you to capture the messages by enabling monitoring profile or by writing custom subflows or using trace nodes.

The most frequently used one is subflows and now a days people use monitoring profile too a lot. There are companies which do not have logs at all ( don’t know how they survive).

Have you ever used Record & Replay? If not, just google to get some basic idea on how that works.

This post is also utilizing the same Record & Replay concept but it does on the fly. I do not have any database setup to store the messages permanently. Just going with built-in capacity of the Integration node.

Let me put here the sequence of steps to achieve this

  1. Enable recording
  2. Enable Injection
  3. Retrieve Recorded Message

Let me put here the Java APIs used here

public void enableRecording(ExecutionGroupProxy proxy, boolean status) throws ConfigManagerProxyLoggedException, ConfigManagerProxyPropertyNotInitializedException {
		
		if (status) {
			proxy.setTestRecordMode(AttributeConstants.MODE_ENABLED);
		}else {
			// clear recorded data and reset server to turn off recording and injection
			proxy.clearRecordedTestData();
			proxy.setTestRecordMode(AttributeConstants.MODE_DISABLED);
		}
		
		enableInjection(proxy, status);
	}
	
	public void enableInjection(ExecutionGroupProxy proxy, boolean status) throws ConfigManagerProxyLoggedException, ConfigManagerProxyPropertyNotInitializedException {
		
		if (status) {
			proxy.setInjectionMode(AttributeConstants.MODE_ENABLED);
		}else {
			// clear recorded data and reset server to turn off recording and injection
			proxy.setInjectionMode(AttributeConstants.MODE_DISABLED);
		}
	}
public List<RecordedTestData> retreiveRecordedMessage(MessageFlowProxy mf) throws ConfigManagerProxyPropertyNotInitializedException, ConfigManagerProxyLoggedException {
		
		Properties filterProps = new Properties();
		String name = getApplication(mf).getName();
//		System.out.println(name);
		if (name != null) {
			filterProps.setProperty(Checkpoint.PROPERTY_APPLICATION_NAME,name);
		}else {
			name = getLibraryProxy(mf).getName();
			if (name != null) {
				filterProps.setProperty(Checkpoint.PROPERTY_LIBRARY_NAME,name);
			}
		}
//		System.out.println(mf.getName());
		filterProps.setProperty(Checkpoint.PROPERTY_MESSAGE_FLOW_NAME,mf.getName());
		
//		ExecutionGroupProxy egProxy = mf.getExecutionGroup();
//		List<RecordedTestData> dataList = egProxy.getRecordedTestData(filterProps);
		
		return mf.getExecutionGroup().getRecordedTestData(filterProps);
	}

That’s it. Once you enable recording, the message flow automatically turns into like this

The recorded message is here (I’ve a UI to make this easier to read)

Here is the local environment message

<localEnvironment xmlns:iib="http://com.ibm.iib/lt/1.0" iib:parser="MQROOT" iib:injectable="true">
   <MQTT>
      <Input>
         <Retained iib:valueType="BOOLEAN">FALSE</Retained>
         <QualityOfService iib:valueType="INTEGER">0</QualityOfService>
         <Topic iib:valueType="CHARACTER">IBM/IntegrationBus/default/Monitoring/Hello</Topic>
         <Duplicate iib:valueType="BOOLEAN">FALSE</Duplicate>

</localEnvironment>
