Hi, We are kicking off a NiFi flow with the ListDatabaseTables processor and we experienced an incident where this processor failed to run. This was due to a network adapter error which seems to have been caused by a restart to NiFi, re-enabling the controller service fixed this issue. However, this is a scheduled job and I would like the flow to be able to respond to an error. The ListDatabaseTables processor will not produce a flowfile when it fails, it has no failure path. Is there a way in which I could add a cron driven processor to send an email if a flowfile doesn't flow through it by a certain time? I can't think of any other solutions that could be possible within NiFi. Any ideas would be appreciated. Thanks, Peter
