Let’s say I have a variable Currency
which is derived from a prometheus query, which I can use to filter the dashboard. For this example let’s assume it contains [USD, EUR, CHF, YEN]
Then there is a second variable Rates
of type custom which contains these key/value pairs: [USD:1.0, EUR:0.8, CHF:0.9, YEN:105.0]. This variable is set to hidden, because I don’t want it to be used as filter.
Now the question is, how can I use the Rates
variable within a query?
-
account_balance{account="Bank", symbol="$Currency"} * ${Rates:$Currency}
or account_balance{account="Bank", symbol="EUR"} * ${Rates:EUR}
If this does not work, is there a way if I define the rates as separate variables so I can access them dynamically?
account_balance{account="Bank", symbol="$Currency"} * ${$Currency}
Kind regards
Danny
