Counters in NiFi are removed after restart

Counters in NiFi are removed after restart

New Contributor

I'm using NiFi 1.9.2 and noticed that after restart all counters are lost. I'm trying to understand where are counters stored in NiFi and is it possible to restore them after restart?

I've found nothing in documentation and configurations. Also there is not endpoint in API to set/create counter (just endpoint for resetting it to 0).

Did anybody faced such issue and how did you handled it?
