Hi Juan, Thanks for your quick rely. The partition where the logs are stored is not full, and as soon as I change ‘fileNamePattern’ to a working on (default or 'nifi-app_%d.%i.log.gz' for example), I see lines appending to nifi-app.log file (tail –f nifi-app.log) So there’s something I don’t get.

To do this, I’ve updated ‘conf/logback.xml’ file by this default configuration: <appender name="APP_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> … <fileNamePattern>${org.apache.nifi.bootstrap.config.log.dir}/nifi-app_%d{yyyy-MM-dd_HH}.%i.log</fileNamePattern> … </appender> To this one <appender name="APP_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> … <fileNamePattern>${org.apache.nifi.bootstrap.config.log.dir}/nifi-app_%d.log.gz</fileNamePattern> … </appender> However, since I’ve updated `conf/logback.xml`, nifi-appl.log is not updated anymore and not new file is created. I’ve tried different patterns and the following are working ok (log append to nifi-app.log): 1. 'nifi-app_%d.%i.log.gz' 2. 'nifi-app_%d{yyyy-MM-dd_HH}.%i.log.gz' But either 'nifi-app_%d{yyyy-MM-dd_HH}.log.gz' nor nifi-app_%d.log.gz are working. It there a reason for that? Sounds like the ‘%i’ in the fileNamePattern is required, whereas it is not the case for ‘nifi-user.log’ for example, this configuration ‘nifi-app_%d.log.gz’ is working ok, logs are appended into ‘nifi-user.log’ Thanks for any help Emmanuel C2 - Restricted # " Ce courriel et les documents qui lui sont joints peuvent contenir des informations confidentielles, être soumis aux règlementations relatives au contrôle des exportations ou ayant un caractère privé.
