Obtain last 500 logged messages

We are using SLF4J/Logback combination to perform our logging. One of the requirement we have is if anything fails, send an email to support/dev group with last 500 logged messages.

I was trying to go through the documentation, but haven't found anything relevant.

One of the approach, I can think is obtain the current log file name, read the file and send last 500 records. But I dont know how to get the current log file name. anyone knows how to? or any other better option to retrieve the log tail?

Thanks

  • It sounds like Log4j's SMTPAppender has the features you require. You could look at its source code as model to guide your own implementation if Logback lacks a similar appender (which would be somewhat surprising).

    Essentially, this email appender has a ring buffer of log events. When a triggering event occurs (by default, an event at ERROR level or worse), the buffer is flushed to an email and sent.
