NiFi component status history not showing more than a days worth of data

["Garland, Michael R" <mi...@lmco.com>]

Hi,

We're trying to make use of the 'EmbeddedQuestDbStatusHistoryRepository' implementation of the Status History Repository within NiFi 1.17.0, but cannot seem to get this feature working as what is described within the NiFi admin guide.

What we are seeing is that the component Status History viewer within NiFi only ever displays 1 days' worth of data, regardless of the configuration of the  'nifi.status.repository.questdb.persist.component.days' value (leaving the default value of 3)

A second point, clicking on the 'Node Status History' button from the hamburger symbol doesn't load any information on a 6 node cluster that has been running for a few days and has ~600MB worth of QuestDB data on each node (with the 'nifi.status.repository.questdb.persist.node.days' value left at its default of 14 days).  After approx. 75 seconds, NiFi displays a parse error, with no information in the logs that would explain the cause.  Has anyone seen this behaviour?

Many thanks,

Michael
