The OnixS C++ FIX Engine logs its data into FixEngineLog.txt
file located in MsgStorage
subfolder of the current (for executing application) folder.
For each FIX session with a file-based session storage, the following files are also created in the MsgStorage
folder:
SESSION_NAME.summary
contains both inbound and outbound FIX messages.SESSION_NAME.state
contains session state-related data.SESSION_NAME
is formed on the base of values returned by OnixS::FIX::Session::senderCompId, OnixS::FIX::Session::targetCompId, session's dictionary FIX Version (OnixS::FIX::Dictionary::version) and a timestamp. During the run-time, it's available via OnixS::FIX::Session's string casting to overload.
