Is there a kind of "If/else" available in "eval" nodes?

[jdursel]

Hello,

I would like to do something like if/else to store a state in a new output measurement.

data
|eval(lambda: if "value" gt 18 then 1 else 0).as("active")

Is it possible?
Thank you
John.

Kapacitor "0.12"

@jdursel I think you can do something like this:

lambda: "value" > 18

Then active will be boolean.

And if you want to use and int type instead of boolean just convert it:

lambda: int("value" > 18)

Which will output a 1 or 0 accordingly.

Hello,
Thank you for your answers. Unfortunately, this doesn't work.
The first one gives : expression returned unexpected type bool
The second one gives : error calling int: cannot convert bool to integer
I didn't try with float(), but i don't expect it to work better :-)

It is probably due to the version of kapacitor 0.12

I think it is the same kind of issue as : #501

Correct the suggested solutions require 0.13 or greater. Also #501 should
be closed, as it was already implemented in 0.13.
