Two questions about Kandula2

[Jimmy]

Hi, everyone:
  First, I want to take a look at messages exchanged in Kandula2 ,but how? I've 
tried tcpmonitor, but it doesn't work well.
    Second, I found a file named endpoints.conf which contains ten properties. 
Can anybody tell me what does these properties stand for and how they are used, 
espeically for these four:
    host=127.0.0.1
    port=8081
    tcpmon_enable=false
    KANDULA_LISTENER_PORT=5050

  Thanks in advance!
