nifi 1.11 /metrics and prometheus question

Hello,

In the data produced by /metrics, I can see aline

# HELP nifi_backpressure_enabled Whether backpressure has been applied for this component. Values are 0 or 1

However I don't see any data related to backpressure, even though I am pretty sure there should be some backpressure data.

Do I need to turn this ON (nifi_backpressure_enabled), or some other property? If so where? I don't see anything related to this on Prometheus reporting task.

Thanks

Sorry my bad, I am suing 1.12.1. The issues states that it was fixed in 1.12. May be in the later version of 1.12. Let me see

Thanks

You might be running into NIFI-7379 [1] where the different Prometheus components are writing to the same registries. If you upgrade to a later version of NiFi you should see the correct data.
