Sniff HL7 messages

Hi! Is there any tool or method I can sniff HL7 messages from openmrs or to openmrs from dcm4chee. I want to look at what kind of message does it recieve and send. PLEASE guide me.

Openmrs version 1.9.7

Thanks in advance.

From your local openmrs installation, is this of help? http://localhost:8080/openmrs/admin/hl7/hl7InArchives.htm
