@hckorkmaz01  While you are currently still using Apache NiFi 1.x major release version, it has reached end of life and is no longer receiving contributions.  As such components will not get library updates or security fixes going forward.   Apache NiFi 2.x is currently active major release being contributed to in the community.  The PrometheusReportingTask was deprecated in Apache NiFi 1.x and officially removed in Apache NiFi 2.x major release.   So I would avoid using it as you will eventually need to move to Apache NiFi 2.x to maintain a secure supported product release.  But technically, this reporting task, while not well maintained in the community, is capable of creating a prometheus endpoint which exposes metrics for all components (includes connections) for consumption. That being said, Cloudera has taken steps to create Cloudera versions of many of the deprecated and removed components in Apache NiFi 2.x; as well as, introduced many components not available at all in any Apache release version (PrometheusReportingTask is not one of them that was retained). https://docs.cloudera.com/cfm/4.11.0/nifi-components-cfm/components/ NOTE:  You are already using a considerably older Apache NiFI 1.18 release.  Many bug fixes and CVEs security issues have been addressed since that release.  If you cannot yet move to Apache NiFi 2.x, you should at least be on the most recent release of Apache NIFi 1.28.

Hi everyone, I hope you’re doing well. I am working on a dataflow in Apache NiFi 1.18, and I need to retrieve the queue size information (flowfile count and content size) directly within NiFi itself, not via an external script or Postman. I know that the NiFi REST API provides this data, and I can access it successfully using external tools. However, my goal is to access queue metrics from inside NiFi, for example through processors like InvokeScriptedProcessor, QueryNiFiReportingTask, or any other built-in mechanism, without sending an external REST API request from outside NiFi. Is there a recommended approach, processor, or reporting task that allows NiFi to read its own queue sizes internally? If not, what would be the best practice to achieve this? Any guidance or examples would be greatly appreciated. Thank you in advance!     ... View more
