Invoke custom code after RollingFileAppender append()

Hi log4jusers,

Want to invoke custom code(to send email) after the RollingFileAppender
append event.

What would you suggest?

P.S. Cannot extend RollingFileAppender, as it is final.

Please help

Thank you,
Gaurav

OK, but in that case using an Action is the correct approach as you responded. It will get control just after the gzip file is created. If you want to support scripting then we could create a ScriptAction.

At least, I think the intention is to send email on rollover, based on this SO comment https://stackoverflow.com/questions/39137396/how-to-extend-log4j2-rollingfileappender/39141257#comment96203788_39141257

Correct. I want the Appender to append an event and then send an email with my custom code.

That isn’t what was asked for.  He asked to send an email after the appender appends an event.

Ralph,

I guess then the question becomes: how can the filter detect that a particular event triggered a rollover?

I don’t think I understand this requirement. Why couldn’t they just create a filter that sends the email. Sure, it won’t be right after the event is logged but so what?

Maybe we should introduce the ability to inject a custom class pre and post
even processing? We could provide an implementation based on the scripting
API so folks could just write JavaScript directly in the config.
