Hi guys,
I'm trying to configure the nifi-app.log rotation process by decreasing the
rotation time and compressing the final rotated file.
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
