Hi Everyone, Can Anyone help us in fixing the issue: I have a flow where I am using control rate processor to control the data flow, I will submit tasks in druid using those files, for example let's say I have a total of 10 files. I will first ask my control rate processor to send 2 flow files to downstream, now I will submit those files as tasks in druid and fetch their status, if 1 task is running and another one is success I need to ask my control rate processor to send only 1 file, if 2 tasks are running dont submit tasks until they are completed, if 2 are success then send 2 files from control rate an counting the tasks which are running and adding them to an attribute,so is there a way that control rate processor takes the value of count attribute in Maximum rate property. I've checked the Rate Control Criteria property which can be set to Attribute Value but I am confused how to set the rate to attribute value.

Yes, whenever we are seeing slowness increasing the concurrent tasks to 6 to 7 but still I am not seeing that much difference, at some time it will be better when increased concurrent tasks. This behaviour is mainly seen for Replace Text processor.

Hi Matt, Thanks for the inputs. Below are the Garbage Collection statics for our Environment of Nifi. Could you please check and let us know any tuning that can be done at this area to increase the performance.

Hi Matt, Thanks for sharing the insights. We are using 3 node cluster and each cluster having 16cores and we have set timer driven thread count to 160. And seeing core utilization as 8%. when we are getting huge data like 2 GB in one flow, the ingestion is becoming dead slow though increase in threads.

Hi Team, We are facing Nifi performance issues form a while as we increased no of processors and processor groups. We have increased thread count but still facing the issue. CPU utilization is also not reaching minimum level it is utilizing less than 50%. How to increase the performance in Nifi. We have been using 13.2 version till now and migrated to 18.0 to see if there is performance improvement but still facing the same. Could anyone suggest how to improve performance.

Hi Team, We are trying to enable logging at each processor group level. But we are unable to do it. From nifi-app.log we are getting as a general but we need log for each processor in a processor group level. We cannot use bulletin as well as bulletin will stay only for 5 min interval. Can anyone can help achieving it.
