SELECT * FROM "example" WHERE "fieldName" = 'value' checks if the field
fieldName is equal to
value. How can I do the same in Flux?
Welcome! Thanks for your question and for giving flux a try
from(bucket:"example-bucket") |> range(start:-1h) |> filter(fn: (r) => r._measurement == "cpu" and r._field == "usage_system" and r.cpu == "cpu-total" )
Use the Filter function.
