Nifi : Alert mail to be sent when file not found in folder

Is there a way using Nifi to poll a particular folder for a file .

If file not found in that interval ,send a mail .

Get File allows read a file ,but there is not failure relationship when using getFile processor.

How can that be achieved ?

Put a MonitorActivity processor after your GetFile processor. Set the threshold to your interval. If a file is not found in that interval MonitorActivity will be triggered.

Template attached. I am using Nifi 1.3.0. In this template if a file is not found in GetFile processor every 10 seconds an event will be generated. You can put an email processor in front of Monitor Activity to send mail. You can also set custom subject headers in Monitoring processor (also in the template).
