Centralizing logs

Python comes with the logging package, which lets you stream logs to a variety of places including standard out, rotating log files, syslog, or a TCP or UDP socket.

There's even an SMTP backend. In the following example, the email_errors decorator will send an email every time an exception is happening in the decorated function. Note that the handler is doing a telnet session with the SMTP server to send the email, so if there's any issue during that session, you might get a second exception when the logger.exception() function is called:

    import logging 
    from logging.handlers import SMTPHandler 
 
    host = "smtp.example.com", 25 
    handler = SMTPHandler(mailhost=host, fromaddr="[email protected]", 
                          toaddrs=["[email protected]"], 
                          subject="Service Exception") 
 
    logger = logging.getLogger('theapp') 
    logger.setLevel(logging.INFO) 
    logger.addHandler(handler) 
 
    def email_errors(func): 
        def _email_errors...
