Subject Re: way to gracefully terminate a processor on errors
Date Wed, 07 Nov 2018 06:53:13 GMT
Hi Chandrashekaran,

You can use the logic which i generally use to stop/start and monitor
failures from either relationship or bullentins. Use Reporting Tasks from
Global Menu - Controller Settings to monitor bulletins, memory use and other
critical information. These reporting tasks needed to be configured with
certain ports which gets triggered whenever there is a active failures
(bullentins, memory use etc). Connect the configured ports to your dataflow
which handles stopping the processors you would want on failures. Stopping
processors can be achieved through NiFi REST APIs.

Further, there is a nice blog from Pierre on configuring reporting tasks.
