I’m trying to convert one of my Grafana dashboards to use Flux as it provides features I need.
First thing I need to do is to get variables Flux way, so I’ve converted
SHOW TAG VALUES FROM promo WITH KEY = utm_source
|> range(start: -7d)
|> filter(fn: ® => r._measurement == “promo”)
|> keyValues(keyColumns: [“utm_source”])
But the response I get is this:
,no columns matched by keyColumns parameter,
I don’t see obvious place I’ve messed up with spelling or something like that, so I think I might’ve misunderstood the docs in some way.
