Count of currently active jenkins agents

Is there an easy way to get a count of how many agents are currently up? I know I can go to www.myjenkins.com/computer/ to see the agents, but counting them manually is tedious.

Is there an API call or something I can run in the script console that just outputs the count for me?

You can sufix computer/ with api/json and run some script on this response. Count the computers array or group by some one of his attributes, like idle or offline.
