[Quickfix-developers] How to suppress 35=X messages in log file

[Gunnar H. <gh...@hi...>]

Hi All,

I want to suppress the 35=X messages in the FIX.4.2-<X>-<Y>.messages.current.log files and log all other messages (administrative, marketdatarequestrejects, etc.).

It would be easy if i could derive my own Session class from FIX::Session and override the sendRaw/send methods to not make the m_state.onOutgoing( string ) call for these message types but this ssems not possible (because in acceptor class the sessions are created from calls to a locally defined SessionFactory variable).


What i could try is  deriving from ScreenLogFactory (say MyScreenLogFactory), override in that class some create() method(s) to create not a ScreenLog but a derivation (say MyScreenLog) of it and in that derived class override onOutgoing(). But then I must search in the message string for subsstrings like 35=X which is a waste of time since in FIX::Session send methods is available the MsgType.

Also some periodically running script to truncate the log files is far from optimal for obvious reasons.


I am perhaps missing something simple because I cannot imagine that writing each 35=X to log file is acceptable for other users of QF (for us it is really a show stopper, log files get toooo big).


Thanks for reading and for any help,
Gunnar
