Fisher provides some basic statistics on your running application. These can be easily used to check the status of the application via a data endpoint for example.
Fisher is available via Clojars.
(ns my-namespace
(:require [fisher.core :as stats]))
(println
(stats/general))I got this code off a link on Twitter that I've now forgotten, but found it so useful I didn't want to just copy/paste it between projects. So here it is.
