@Bharadwaj Bhimavarapu There are no attachments to the question. Can you please check again? Do you see any error message on the processor or in the bulletin board, or in nifi-app.log?

Can you also share a screenshot of your GenerateFlowFile "scheduling" and "settings" tabs as well. Is this the only flow on your graph? Anything odd in the nifi-app.log when you start the processor?

@Bharadwaj Bhimavarapu

If you want to have the processor run every 5 seconds, then you would set that using property "Run Schedule" under the Schedule tab like this

Along the menu bar at the top of the NiFi UI is there is a field that shows the current number of active threads in your NiFi.

Is this a standalone NIFi install or a multi-node NIFi cluster?

Under "Controller Settings" found within the hamburger menu in the upper right corner of the UI, What do you have configured for "Maximum Timer Driven Thread Count" and " Maximum Event Driven Thread Count"?

I am wondering if you have some other processors in your NIFi holding all your available threads so this processor cannot get one.

Thanks,

Matt
