Are you attempting to also attach a screenshot? My Email seems to think so but no photo is coming out. The zero tasks makes sense (see below) but I am not 100% sure where your getting 30 seconds from, maybe another dev has an idea on that one... Can we get a screenshot?
~~ Ran on 1.1.1... Zero tasks makes sense as there has been no work scheduled for the processor. Otherwise there is no need to run something like the UpdateAttribute Processor nonstop each time. I went and turned the processor logger to INFO from WARN (bottom of email) and you see the Timer-Driven Process thread only log once a flowfile has landed into the channel. Otherwise for 5 minutes after zipo if no new FlowFiles landed in the channel. If we look at the dev docs it mentions mostly the onTrigger and what 'work scheduled means' (when processors are triggered) https://nifi.apache.org/docs/nifi-docs/html/developer-guide.html#when-processors-are-triggered Quote from the docs "A Processor’s onTrigger method will be called only when it is scheduled to run and when work exists for the Processor. Work is said to exist for a Processor if any of the following conditions is met: *A Connection whose destination is the Processor has at least one FlowFile in its queue *The Processors has no incoming Connections *The Processor is annotated with the @TriggerWhenEmpty annotation" If you keep going they talk about annotations, you could use the onScheduled annotation if you always wanted to execute the task in a custom processor. #INFI UpdateAttribute Processor Logs 2017-03-31 08:21:22,393 INFO [StandardProcessScheduler Thread-3] o.a.n.c.s.TimerDrivenSchedulingAgent Scheduled UpdateAttribute[id=24478d36-015b-1000-ce38-ca50c24234fd] to run with 1 threads 2017-03-31 08:21:22,570 INFO [Flow Service Tasks Thread-2] o.a.nifi.controller.StandardFlowService Saved flow controller org.apache.nifi.controller.FlowController@706b2b31 // Another save pending = false 2017-03-31 08:21:34,666 INFO [StandardProcessScheduler Thread-6] o.a.n.c.s.TimerDrivenSchedulingAgent Scheduled GenerateFlowFile[id=244774ca-015b-1000-5a1f-9cd57db06ec3] to run with 1 threads 2017-03-31 08:21:34,712 INFO [Timer-Driven Process Thread-5] o.a.n.p.attributes.UpdateAttribute UpdateAttribute[id=24478d36-015b-1000-ce38-ca50c24234fd] Updated attributes for StandardFlowFileRecord[uuid=74742b13-a650-4e19-a2e4-5a8adbfc259d,claim=,offset=0,name=82058058092238,size=0]; transferring to 'success' 2017-03-31 08:21:35,077 INFO [Flow Service Tasks Thread-2] o.a.nifi.controller.StandardFlowService Saved flow controller org.apache.nifi.controller.FlowController@706b2b31 // Another save pending = false 2017-03-31 08:21:36,865 INFO [Provenance Maintenance Thread-2] o.a.n.p.PersistentProvenanceRepository Created new Provenance Event Writers for events starting with ID 8 2017-03-31 08:21:36,898 INFO [Provenance Repository Rollover Thread-1] o.a.n.p.PersistentProvenanceRepository Successfully merged 16 journal files (2 records) into single Provenance Log File ./provenance_repository/6.prov in 34 milliseconds 2017-03-31 08:21:36,899 INFO [Provenance Repository Rollover Thread-1] o.a.n.p.PersistentProvenanceRepository Successfully Rolled over Provenance Event file containing 2 records.
