Hello

Thanks for the answer. I am still a bit confused.

If the logback FileNamePattern is "app.log.%d{yyyyMMdd_HHmmss}Z.log", would this by default mean its going to rollover every second? In other words , does the fileNamePattern define the rollover schedule?

You mention using "yyyy-ww" to trigger a weekly Rollover, would this mean the fileName pattern should be made

"app.log%d{yyyy-ww}Z.log" ?

Is it possible to decouple the Name of the Rolled over log file and the tiriggering of RollOver ? What if Iwant a rollover every week , but the name of the Rolled Over file to have hhmmss as part of it? I Sorry if I have caused confusion here

Best Regards

Ani

Hi Ani,

Logback does not support cron-like triggering. However, it supports
triggering based on a date pattern, e.g "yyyy-MM-dd"

The schedule "0 0 * * 1 ?" corresponds to first day of the week at
midnight. The pattern "yyyy-ww" corresponds to the same triggering
schedule.

The link below provides more details:

I hope this helps,
