How to make log4j send emails asynchronously

[Pramode C.E]

Hi,

I am using log4j (ver 1.2.16) to send ERROR logs to a gmail id ... the problem is that whenever there is an error, processing

gets slowed down (which is I guess because the logger tries to contact the SMTP server and everything is blocked until SMTP

processing is complete). There seems to be some kind of "AsyncAppender" feature to log4j, but I don't see any documentation

as to how this can be used from log4j.properties. Has somebody encountered this issue before? If so, it would be great to know how

you got this fixed!

Regards,

Pramode

You need to send emails in a job. http://www.playframework.org/documentation/1.2.3/jobs

You basically just create an instance of the job class and tell it to
run immediately using the now() method.

Did you look at this page :

An async appender references the smtp appender, so it sends email
asynchronously

You can also use BufferSize to batch send email :

Thanks for the link!

In the link above, XML files are being used for configuring log4j; I am trying to find out if there is a way to do this using log4j.properties. 

You can also use BufferSize to batch send email :

http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/net/SMTPAppender.html

If BufferSize = N, then log4j will keep N logging events in a buffer and send out an email only when the N'th event is received; but  again, once the mail sending process gets started, I think all other activities will get suspended till all the mails are sent ... this will again introduce a delay! The only way to tide over this problem seems to be using the AsyncAppender ...

Thanks and Regards,

Pramode

it only works with xml-config. Notice that your xml-config must name
log4j.xml, so that log4j grep it automatically see

Thanks for the clarification; so it seems I have to use the xml config itself!
