Hi,
I have a small question regarding boost.log: would it be possible to 'register' different outputfiles for different loggers?
BOOST_LOG(get_normal_log()) << msg; // goes to 'normal.log' BOOST_LOG(get_special_log()) << msg; // goes to 'special.log'
Filtering is the key. If each of your loggers has an attribute with a unique value, you can write filters that will pass records from the particular loggers to the particular sinks. That way you can create several file sinks that will write records from their respective loggers. Alternatively, you can use the multi-file sink [1]. In that case you only need one sink, which will distribute records to different files, which names will be based on the attribute values attached to the record.
