I have a watcher that is configured to monitor 2 inputs. The payload of input 1 is compared with the payload of input 2. I want to set the watch condition such that if the payload of input 1 != payload of input 2, check first that the payload of input 1 is not empty before sending out an email notification.

The reason for this is because the e-mail template for the watcher is populated with values based on the payload of input 1 and I don't want the watcher to send out notification emails where the contents are empty because the payload of input 1 is empty. So in this case, I imagine that some kind of multiple condition watcher needs to be configured but I'm not so sure how to set such a thing up. Any ideas on how to implement something like this?

Hey,

if you paste your current watch and the data you are trying to query or write a condition for, it would be much easier to help, now everything is pretty abstract - I'll try my best though 🙂

So far, this sounds like you need to have a watch with a chained input, that gets the data for input1 and input2, then have a condition that checks if payload2 equals payload1 and is not empty, and based on that, sent out the email.

By using a [script condition](https://www.elastic.co/guide/en/x-pack/5.0/condition-script.html) you can easily implement the above check.

Yup, I'm currently using a chained input for my watcher. Would it be possible for you to provide an example script condition that can implement what I'm trying to do?

    }
  }
}

```

Hope this helps

Hi @spinscale thanks for the reply. In the end, I used a totally different approach to implement my watcher. Appreciate the answer though.
