How to add email notification?

[cailiang9]

I found a way on web using logging handler: http://stackoverflow.com/questions/6182693/python-send-email-when-exception-is-raised . But I think we also need a delay(2m, 4m ... 1h to prevent too much notifications) and cache to send logging notifications to users. When the # (last sent logwarning) < 10 (system may be back to normal), the delay is reset to 2m again.

Seems like a logging problem, not a retry problem.

Not saying this is a way to implement it, but it can be using by implementing whatever logic you want for email buffering/aggregation/flood protection in flush method of custom logging handler.
You can use https://github.com/mikecharles/python-buffering-smtp-handler/blob/master/buffering_smtp_handler.py#L16 as inspiration.
