Hi Bryan, I mean none of these files are getting rolled over. For APP_FILE, there are no nifi-app_2016-10-04_01.log getting created (on hourly basis), and everything goes into a single nifi-app.log file only. I tried changing it to minute level, still it didn’t work. Also, I tried setting the log directory to a hardcoded “logs” like it used to be in 0.3. Still, no success.
I am wondering if this could be because of running NiFi on windows.

I just tested the nifi-app.log by running NiFi for over an hour and it rolled exactly at 4pm and ended up with: nifi-app.log nifi-app_2016-10-04_15.0.log The current hour will always be in nifi-app.log. The boostrap and user logs are set to roll per day, so you would have edit their fileNamePattern to include %d{yyyy-MM-dd_HH} rather than just %d if you wanted them to roll per hour. -Bryan On Tue, Oct 4, 2016 at 10:12 AM, Manish Gupta 8 <[email protected]<mailto:[email protected]>> wrote: Hi Bryan, My app-log settings look as following, but the file is definitely not getting created every hour.

The logback.xml contains some comments that explain how to change it for different rollovers: https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-resources/src/main/resources/conf/logback.xml#L24-L30 The nifi-bootstrap.log looks like it is set to daily because it only has %d https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-resources/src/main/resources/conf/logback.xml#L71 Thanks, Bryan On Tue, Oct 4, 2016 at 9:57 AM, Manish Gupta 8 <[email protected]<mailto:[email protected]>> wrote: Hi, Is there any documentation/example for setting rolling app and bootstrap log file. I want NiFi to create a new file every one hour. By default, everything goes into a single file. I couldn’t find much about logback.xml in admin/dev guide. Thanks, Manish
