Limiting log4j SMTPAppender
Jump to Comments
I wanted to set a maximum amount of e-mails that SMTPAppender would send after filling up a mailbox with 30,000 damn e-mails.
Turns out it was pretty damn easy, I set up my appender in a java class, and the SMTP appender has a method called setEvaluator that takes an instance of TriggeringEventEvaluator, so I just created a quick inner class like so.
class LimitingEvaluator implements TriggeringEventEvaluator
{
private int sentEvents = 0;
private int MAX_EVENTS = 20;
@Override
public boolean isTriggeringEvent(LoggingEvent arg0) {
sentEvents++;
if(sentEvents>= MAX_EVENTS)
return false;
return true;
}
{
private int sentEvents = 0;
private int MAX_EVENTS = 20;
@Override
public boolean isTriggeringEvent(LoggingEvent arg0) {
sentEvents++;
if(sentEvents>= MAX_EVENTS)
return false;
return true;
}
}
and when i set up my appender I do this
appender.setEvaluator(new LimitingEvaluator());
