Tufteallows you toeasily monitor the ongoing performanceof your Clojure and ClojureScript applications in production and other environments.
It providessensible application-level metrics,and gives them to you asClojure datathat can be easily analyzed programatically.
Carte Figurative,one ofEdward Tufte's favourite data visualizations.

- Small,fast,cross-platform Clojure/Script codebase
- Sensibleapplication-level metricswithout the obscure JVM-level noise
- Metrics as Clojure maps:easily aggregate,analyse,log, serialize to db, etc.
- Tiny,flexible API:
p,profiled,profile - Greatcompile-time elisionandruntime filteringsupport
- Arbitrary Clojure/Scriptform-levelprofiling
- Full support forthread-localandmulti-threadedprofiling

;;Request to send `profile` stats to `println`:
(tufte/add-basic-println-handler!{})
;;; Define a couple dummy fns to simulate doing some expensive work
(defnget-x[] (Thread/sleep500)"x val")
(defnget-y[] (Thread/sleep(rand-int1000))"y val")
;;Let's check how these fns perform:
(profile;Profile any `p` forms called during body execution

(dotimes[_5]
(p:get-x(get-x))
(p:get-y(get-y))))
