"getting the data in"

"Hello metric"(Python)

import timeimport socketdef collect_metric(name, value, timestamp): sock = socket.socket() sock.connect( ("localhost", 2003) ) sock.send("%s %d %d\n" % (name, value, timestamp)) sock.close()def now(): int(time.time())collect_metric("meaning.of.life", 42, now())

"Hello metric"(Clojure)

(import [java.net Socket] [java.io PrintWriter]))(defn write-metric [name value timestamp] (with-open [socket (Socket. "localhost" 2003) os (.getOutputStream socket)] (binding [*out* (PrintWriter. os)] (println name value timestamp))))(defn now [] (int (/ (System/currentTimeMillis) 1000)))(write-metric "meaning.of.life" 42 (now))
