Nifi slack alert with dynamic message

[#1]

Hi All,

I am trying to send slack alerts from Nifi whenever there is a failure in flow.

I have some 10 different processor flows, I want to use a single putslack for all those flows but the message in slack is dynamic..

Example:

record failed for processor1

record failed for processor2

meaning just a variable changes in slack message.

and this variable i should send from processor flows.

How can putslack processor know from which previous processor it got the request ?

But I don't know how to make it possible. I kept a output port that collects all flowfiles of failures. 

Now i created a putslack processor that connects to this output port.. but i dont see a option on how can i send variables dynamically.

Can someone please guide me with suggestions, or correct me if this ideation is wrong..

Just wanted to update that I used flow file attributes to solve this.

putslack's Webhook Text supports expression language!!!
