Summary: Add Queue Logging to ListenTCP
Key: NIFI-9654
URL: https://issues.apache.org/jira/browse/NIFI-9654
Project: Apache NiFi
Issue Type: Improvement
Reporter: David Handermann
Assignee: David Handermann
The {{ListenTCP}} processor maintains an internal queue of events received,
which the processor polls during {{onTrigger}} invocation. This approach
allows the framework to control FlowFile creation, but it can also result in
large numbers of queued events when the framework does not trigger the
processor due to scheduling configuration or resource issues. To provide basic
tracking and troubleshooting, implementing debug logging of current queue size
and largest queue size at a regular interval would be helpful.
