is there any way of returning a 0 or 1(boolean) on the basis of a value of a time series metric in Prometheus?

Question

is there any way to return a boolean value when a time series that has a threshold of 2s is crossed, The metric is usually 0, but if a threshold of 2 is crossed, the return should be a 1?

Answer 1

m >=bool 2
