Hello,
thank you for clarification. I though this :raw was something specific with
histograms/buckets/heatmaps.
In the past I tried adding the "=~" instead of "=" but did not work. tried
again today and it was a combination of things to change I did not before.
I changed it like this and it works like I exect:
host="${target:raw}" ----> host=~"$target"
