Thanks for pointing this out. My bad for not referring to the NiFi documentation. When I saw the Cron Driven and presented with the default "* * * * * ?", my instinct was to reference a standard Linux/Unix Cron format.

In your case, I believe you'd like something like 00 02 10 * * ? Hope this helps. 2016-06-16 19:13 GMT+02:00 Keith Lim <[email protected]<mailto:[email protected]>>: My GenerateFlowFile processor is enabled and started with Scheduling Strategy: Cron Driven Run Schedule : 02 10 * * * ? This I expects to generate a flow file daily at 10:02 am, but from my limited test, it seems to take the second parameter as minutes, and generate a flowfile hourly at 10 minutes after the hour, e.g. 10:10, 11:10, 12:10, 13:10... Perhaps there is a bug in parsing system date format? Attached is a simple template that I am using for testing.

It has to be started and enabled. I guess sharing the cron expression and maybe a quick screenshot will help next.

Sometimes it would fire when not expected to and others not fire when expected to. This is on Windows OS and the processor I tried was GenerateFlowFile. Is CRON Driven setting not designed to work on Windows OS? Thanks, Keith
