WriteAheadProvenanceRepository might be the culprit here. I have another instance running 1.8.0 and it is using PersistentProvenanceRepository. It's been running for months with same flows and has no issues displaying provenance events.
In 1.9.2 PersistentProvenanceRepository is deprecated and by default nifi.properties have nifi.provenance.repository.implementation=org.apache.nifi.provenance.WriteAheadProvenanceRepository From: [email protected] At: 07/12/19 00:42:17To: [email protected] Subject: Re: 1.9.2 Does not show provenance events I have the same behaviour, with the same setup (container, “external” mount to network drive) on 1.9.2 On Thu, 11 Jul 2019, at 21:08, Mikhail Rolshud (BLOOMBERG/ 120 PARK) wrote: This is a clean install of 1.9.2 And I can see the provenance events for a couple of days if I wipe out provenance_repository and restart the node.

Please see in the migration guide from old version you had until now.

I checked the provenance_repository/ folder and I can see files there get modified as events are happening, just can't see anything on UI side.
