Re: [Twisted-Python] Need for multiple loggers...

Thanks but I think that answers the wrong question. In my original application I have three different named loggers (the original app is written in Python). I have logOp, logTrace, logDebug each of which goes somewhere different (for instance logOp messages go to the operators system, logDebug is sent to a non-rotated file and logTrace goes to a rotating log file). Through out my application I will log message to the appropriate logger, for example messages that I want written out to the debug file I write as logDebug.msg(...). Those that I want to trace objects moving around I will do logDebug.info(...). etc. In Twisted.python.log it looks like there is a single logger and I do: log.startLogging(...). What I need to know is how can I create three different loggers in my new application. Do I need to subclass some twisted class? Chaz. Moof wrote:

I have an application that I am converting to Twisted. One of the things the application does is have three different logs running. Each of the three does something different.

In normal python logging I figured out how to have the three different loggers. In Twisted I am not quite sure how to do it. Has someone done this before?

You want to write a class or function that will receive a dictionary with 'system', 'message', and possibly 'failure', 'isError', 'debug' and 'printed', and take appropriate action. You may wish to have a look at twisted.python.log.FileLogObserver. Once you have the function or method, you can do a log.addLogObserver(function).

You can pass things on to the eventDict as keywords to log.msg, log.error, and log.debug (though the last one is deprecated). If you find that isn't enough for you, it's possible to replace the LogPublisher with something that can gather more data, I currently use one that inspects the stack for which module called it, for example.
