'How to get number of nodes running in prometheus

I am trying to create an alert in which, when the number of nodes increase or decrease I'll send an alert.

currently, I can get the node's count using this:

count(kube_node_info)

but I want to get the node's count for 5 mins and 1min so that I can do the subtraction and sent the alert. I don't know how to get the count of nodes for a 5m time frame.

You can use either the delta function or the offset modifier to get what you want.
