I have a status word where each bit has a particular meaning. I need to extract all bits and display messages in Grafana relevant to bit values and generate alerts basing on some extracted bits.
I can't figure out how to extract bits in rows, not in columns, using Flux.
For example, I have integer field Alarm:

And I would like to extract all bits from it like this for further processing:

I know how to extract bits into columns using Flux:
import "bitwise" ... |> map(fn: (r) => ({ r with bit00: bool(v: bitwise.sand(a: r._value, b: 1) / 1), bit01: bool(v: bitwise.sand(a: r._value, b: 2) / 2), bit02: bool(v: bitwise.sand(a: r._value, b: 4) / 4), ... }))
But this gives bits as columns, not rows as I need...
