Re: Analyze : "Diagnostics on Stop" logs

[e-sociaux]

 

Hello Joe,

 

It is a VM with Rocky 8 as OS. We use the systemd to start/stop nifi process

 

The nifi process is die. I could see with the journalctl -u nifi

 

Oct 27 14:53:11 server01 systemd[1]: Started Apache NiFi.

Oct 28 03:31:04 server01 systemd[1]: nifi.service: Supervising process 1399442 which is not our child. We'll most likely not notice when it exits.

Oct 28 07:20:40 server01 bash[1399411]: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

Oct 28 07:20:40 server01 bash[1399411]: NiFi PID [1399442] shutdown started

Oct 28 07:20:40 server01 bash[1399411]: NiFi PID [1399442] shutdown in progress...

Oct 28 07:21:00 server01 bash[1399411]: NiFi has not finished shutting down after 20 seconds. Killing process.

Oct 28 07:21:04 server01 systemd[1]: nifi.service: Main process exited, code=exited, status=143/n/a

Oct 28 07:21:04 server01 systemd[1]: nifi.service: Failed with result 'exit-code'.

 

And I don't see the "Java Heap Space" error in the nifi-app.log so it is a bit weird.

It is why I'm trying to find some informations in the diagnosticts logs

Hello

 

We need to better understand what it means to say the node stopped.  Did the nifi process die?  The nifi-app.log should almost certainly expose something interesting.  Is this on a Linux box, or in a container, etc. How is it run and what precisely stopped?

Thanks

Hello all,

 

I have activated the "diagnosticts on stop" in the nifi.properties.

https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#nifi_diagnostics

My node has stop twice time now but I don't find anything.

 

Have we got some documentations about the log of diagnosticts to find the root cause/ the processor cause the stop ?

 

Regards
