This is because of how NiFi is run. When you startup nifi (bin/nifi.sh start) it doesn’t directly start the NiFi process. Instead, it starts a different processor, which is called RunNiFi. This RunNiFi process is responsible for doing a lot of things, including monitoring the nifi process and if it dies restarting it. Anything written to NiFi’s Standard Out goes to this processor, which then logs it. So you’d probably need to update the logging for the appender writing to the bootstrap file: <appender name="BOOTSTRAP_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender”>
And redirect that to standard out Thanks -Mark On Sep 28, 2022, at 9:48 AM, Kevin Doran <kdo...@apache.org<mailto:kdo...@apache.org>> wrote: Dylan - I looked into this and am yet unable to offer an explaination. Perhaps others that are familiar with how org.apache.nifi.StdOut can shed some light, or else I will keep digging when I have a block of time. To help in my understanding: Which Docker image are you using? Is it the apace/nifi image or a custom one, and if custom, can you share the Dockerfile?

I have NiFi running in a Docker container, which sends all console logs to AWS CloudWatch. Therefore, I am configuring NiFi to send all logs to the console. The problem is, for some reason all log messages are coming from the org.apache.nifi.StdOut logger. I cannot figure out why, since I would like messages to be printed directly from the logger that is receiving them. It seems like messages are "passing through" loggers, which are ultimately printed out from the org.apache.nifi.StdOut logger. Here is an example of one log message: 2022-09-27 10:08:01,849 INFO [NiFi logging handler] org.apache.nifi.StdOut 2022-09-27 10:08:01,848 INFO [pool-6-thread-1] o.a.n.c.r.WriteAheadFlowFileRepository Initiating checkpoint of FlowFile Repository Why would every single log message come from the StdOut logger? And how can I have logs delivered from the logger they're supposedly originally coming from?
