Hi Asanka For a CRON which runs once a day at 7 AM I use this pattern “0 0 7 * * ?”. So I don’t see any reason why your CRON doesn’t work. Can you try with an example like 1 AM instead of midnight and see what’s happening?

NiFi uses the Quartz Cron and not the Linux cron. Every day at midnight is: 0 0 0 * * ?

It seems like nifi cron expressions are quite different. On Tue, Jan 1, 2019 at 11:58 AM Asanka Sanjaya <angal...@gmail.com<mailto:angal...@gmail.com>> wrote: Thanks Chad!

Here is an online cron editor that can help build your cron expressions: https://crontab.guru/ Also here is simple cron tester to see the next n iterations of your cron expression: http://cron.schlitt.info/ -Chad On Dec 31, 2018, at 2:04 AM, Asanka Sanjaya <angal...@gmail.com<mailto:angal...@gmail.com>> wrote: Hello, I use a cron-driven processor to start the workflow and the expression is: 0 0 0 * * ? I expect the processor to run each day at 00:00 hours. But it runs each hour instead.
