Record Data Replication statistics in WebSphere Application Server

If any point you need to record the DRS activity in your WebSphere Applications Server cluster you can set the JVM system property ENABLE_DRS_STATS_LOGGING  to 2 to record Data Replication Service (DRS) traffic statistics
See technote http://www-01.ibm.com/support/docview.wss?uid=swg1PK23862&wv=1

Please note, as the technote says Stats logging is enhanced by providing summary and detailed statistics on outgoing message transmission. These statistics are used for servicability and are not generally collected unless instructed by IBM service.
