Kapacitor: How to get Field name in TICK script

Question

I'm trying to create a TICK script via Chronograf and it works nicely. I have some tags set and some fields. I created an Alert tick file for specific field and I can get its value by doing

{{ index .Fields "value" }}

but I can't get its name...is that even possible?

Thank you!

Well, the name of the field is "value" isn't it? So you already kind of have it. Or I don't understand your question. — Bunyk, Jul 23 '18 at 08:52
Oh, I guess I got you. So you have some datapoints, but don't have names of fields in them? Then I guess I could answer your question. — Bunyk, Jul 23 '18 at 20:24

Fields is a map from string to interface (see source). So you could iterate over that mapping using following template:

{{ range $key, $value := .Fields}}
    Arbitrary text here, but you could for example show all fields
    in the form {{$key}}={{$value}}
{{end}}

That's interesting! – Shvalb Jul 23 '18 at 21:15
by the way, is there a way to add field name and value to the output json alert but not part as "message", but rather as part of `data` ? – Shvalb Jul 23 '18 at 21:17
@Shvalb Don't know, need to figure it out. But community for Kapacitor is very small here on StackOverflow, probably most questions are discussed on on their forum. – Bunyk Jul 24 '18 at 11:31
