Multiple Logging Hierarchies?

Postby jkeogh1413 » 13 Aug 2013, 20:29


I am looking for a unique logging solution.

I will try to explain our design and the issue we are facing.

We have a TCPServerConnectionFactory that spawns a new environment (new set of objects) with each new connection. The spawned environment gets a new socket and has a listening thread. If a message comes in to an established connection a pthread will handle the message. Each useful message that comes in will contain an identifier that will identify all actions that happen until this process is completed by closing the connection and destructing the set of objects that were created for this connection.

Many connections may happen simultaneously. Before moving to a pthreaded environment we were able to use Thread::setName along with the %T identifier to clearly see which log messages were coming from which connection. Now that we are multi-threaded we need a new solution.

I have been unable to find a clean way to make each object that gets spawned through the life of a connection aware of our unique identifier, so a custom log wrapper wasn't very useful.

My next attempt was to use the Logger channel framework to save each connection's logs to a file named by the unique identifier we would receive in a message. The issue here is that if a new connection comes in during the life of another, it will overwrite the channel properties and start pointing logs to a different file.

Using the Logger framework, is there a way for me to have a new Logger hierarchy per connection? Basically, we need the set of objects spawned by the new connection to all use the same logging properties, and to not affect any other set of objects logging properties.

Not sure if this is possible, but thought this would be the place to ask. Thanks!
