Hello, I’m working on two NIFI nodes cluster with NIFI 1.11.4 version. But the Provenance GUI cannot show any items. There is my configuration about the Provenance:
$ grep provenance /opt/nifi-1.11.4/conf/nifi.properties nifi.provenance.repository.implementation=org.apache.nifi.provenance.WriteAheadProvenanceRepository nifi.provenance.repository.debug.frequency=1_000_000 nifi.provenance.repository.encryption.key.provider.implementation= nifi.provenance.repository.encryption.key.provider.location= nifi.provenance.repository.encryption.key.id= nifi.provenance.repository.encryption.key= nifi.provenance.repository.directory.default=/data2/provenance_repository1 nifi.provenance.repository.directory.provenance2=/data2/provenance_repository2 nifi.provenance.repository.max.storage.time=4 hours nifi.provenance.repository.max.storage.size=80 GB nifi.provenance.repository.rollover.time=30 secs nifi.provenance.repository.rollover.size=100 MB nifi.provenance.repository.query.threads=2 nifi.provenance.repository.index.threads=2 nifi.provenance.repository.compress.on.rollover=true nifi.provenance.repository.always.sync=false nifi.provenance.repository.indexed.fields=EventType, FlowFileUUID, Filename, ProcessorID, Relationship nifi.provenance.repository.indexed.attributes= nifi.provenance.repository.index.shard.size=2 GB nifi.provenance.repository.max.attribute.length=65536 nifi.provenance.repository.concurrent.merge.threads=2 nifi.provenance.repository.buffer.size=5000000 This nifi cluster has been running for 2 days. The bellows are the log when I query the SEND event, it should be list some records on Provenance GUI: what is the root cause ‘retrieved 0 events’ and how can I resolve the issue? 2020-10-29 08:56:08,515 INFO org.apache.nifi.provenance.index.lucene.QueryTask: Successfully queried index /data2/provenance_repository2/lucene-8-index-1603930630342 for query +eventType:send +time:[1603900800000 TO 1603987199000]; retrieved 0 events with a total of 22225 hits in 141 millis 2020-10-29 08:56:08,517 INFO org.apache.nifi.provenance.index.lucene.QueryTask: Successfully queried index /data2/provenance_repository1/lucene-8-index-1603929964785 for query +eventType:send +time:[1603900800000 TO 1603987199000]; retrieved 0 events with a total of 20787 hits in 125 millis 2020-10-29 08:56:08,655 INFO org.apache.nifi.provenance.index.lucene.QueryTask: Successfully queried index /data2/provenance_repository2/lucene-8-index-1603889124980 for query +eventType:send +time:[1603900800000 TO 1603987199000]; retrieved 0 events with a total of 22256 hits in 119 millis 2020-10-29 08:56:08,745 INFO org.apache.nifi.provenance.StandardQueryResult: Completed Query[ [SEND] ] comprised of 4 steps in 411 millis 2020-10-29 08:56:08,745 INFO org.apache.nifi.provenance.index.lucene.QueryTask: Successfully queried index /data2/provenance_repository1/lucene-8-index-1603888576272 for query +eventType:send +time:[1603900800000 TO 1603987199000]; retrieved 0 events with a total of 13792 hits in 202 millis Thanks Paul
