log4j SMTPAppender - 通过电子邮件发送多条错误消息

Question

I am using log4j's SMTPAppender to email me upon each exception, but I'd really prefer it to aggregate emails into one email with a batch of errors rather than one email for each error.

I have seen the bufferSize variable but that appears to be for all types of message, not just ERRORS.

Does anyone know how I might achieve this?

Thanks

Answer 1

You can use: log4j.appender.myMail.evaluatorClass to implement the TriggeringEventEvaluator , this way you can programmatically decide when/what messages to send. See: http://www.manning-sandbox.com/thread.jspa?threadID=9913 for more details.

Answer 2

Try adding/using an Evaluator eg below in the configuration:

<evaluator type="log4net.Core.LevelEvaluator">
    <threshold value="ERROR"/>
</evaluator>

Also set lossy attribute to true along with the desired buffer size:

<lossy value="true" />
<bufferSize value="xxxx" />
