How to use Common.Logging.Log4Net to log all messages grouped

So I am using Common.Logging.Log4Net for logging purposes, but since the code is multithreaded, often messages get mixed up, eg:

message from thread 1 message from thread 2 message from thread 1 message from thread 1 message from thread 2

In order to avoid this, we are trying to get all messages together and we print them all when the execution finishes. For that we basically have a list of Action delegates and each contains the log line, eg:

            Log.DebugFormat("Handling...");

But this unfortunately does not solve any issue, because when we write back to the log, messages still get mixed, since all we do is a foreach on the list and execute the delegates. So is there any way to get all the messages written at once?

Sounds like you're looking for some sort of transaction logging. By nature, application logging is sequential.

A couple of options I can think of off-hand:

  • Log the thread id. Use a more appropriate log analyzer when reviewing the output. Excel works fine if you're using CSV or other common format. When you're interested in a certain thread's actions, filter on the thread id. I'd try this route first.
  • Log each thread to a separate file. I've seen Microsoft do this on occasion. Might work ok. Would have to uniquely identify each file somehow. Guessing log4net can handle that.
