Alert Value refers query’s first data.

For example, we have a query with this result.

name price
alpha 5000
beta 2000
gamma 1000
delta 4000
sigma 6000
omega 3000

When we set “price” in the column , the Value will be 5000, the first data.

I think it is better behavior because we have to decide which data we will compare Reference value, but we need the documentation of this behavior.

have you got an answer?

The Alert feature has recently had it’s documentation made thorough https://redash.io/help/user-guide/alerts/setting-up-an-alert
