Nifi - Flow Analysis Rules - Possibility to create custom rules?

brajs — Mon, 12 May 2025 10:13:42 GMT

Hi everyone,

I'm currently working with Apache NiFi 2.1.0 versions, and I'm wondering:

Is it possible to create a custom Flow Analysis Rule, similar to how we can create custom processors?

Thanks in advance for your help!

@brajs Yes, it is possible to make custom flow analysis rules. This is still tech preview in nifi 2.0 so documentation is limited. I would recommend to take a look at some existing rules, tear them down to source code, modify to suit, and build and package your custom rules. Once you have a new rules nar file, just deliver it to the nifi /lib location and it should be available to use.
