Triggering a workflow by an external process/change

Dear all, 

My workflow starts with the CSV reader node. The CSV file is generated by an external process. My question is: How can I trigger the workflow automatically when the source file (the CSV) has changed? Is there a way to trigger  a workflow by an external (to knime)  process?






I can explain a generic solution that I typically use:

It is a cronjob on a Linux system that starts a shell script in a regluar basis. And this shell script can then search for a file or can determine the timestamp of a file. If the condition is true, then the shell script starts the KNIME workflow in a batch mode. 

That's it. Does that make sense for you?




Hi Frank, 

I will try this direction.
