A little warning about the email handler. Remember that SMTPHandler is a single threaded, blocking, logger. If your logging triggers a email then all other logging waits until the email is sent. This can quickly block your entire web app.
We ran into that a couple of days ago. Something caused a logger to log a critical message which the SMTPHandler picked up and mailed to us. When that happened the normal info logging was blocked and some of our timecritical threads started to timeout which in turn triggered other critical logs. :P On Jan 9, 4:48 pm, Jason <[email protected]> wrote: > Can someone help me with my logging configuration?
