Unable to get detailed

Hi All,

    I am using PO7.4. At times I need to look into the message monitoring log in production system.

    I am facing problem in finding the complete log of messages ( from start to end ) in message monitoring .

   Is there anyway to increase the trace as well as keep the log intact for longer period of time . ?

  Please refer to the attachment
