Where are nifi alerts and warning logs and how can I view them?

avatar

I am testing and tuning some data flows. During off hours a processor might fail or files might be lost.

Where are the error logs stored? And where would I find information to correlate an alert or error log to a solution, such as: (see below) ???

Error "Failed to process session due to org.apache.nifi.processor.exception.ProcessException:FlowFile Repository failed to update: FlowFile Repository failed to update"

Warning "Rejecting connection from /x.x.x.x:2000 because max connections has been met"

Error "Successfully sent 2 messages, but failed to send 1 messages; the last error received was java.io.IOException: Message too long: Message too long

Warning "Response time from ip-x-x-x-x... :2000 was slow for each of the last 3 requests made. To see more...

OOM errors

Thank you

The logs should be at /var/log/nifi/nifi-app.log in all the nifi nodes. You can also use Log Search (if it is installed in your environment) to see the pattern and play with the log using UI.
