immutant-hystrix-stream

[]

Clojure stuff for encoding Hystrix commands and providing a data stream via SSE in Immutant applications.

Usage

(ns my-immutant-app
    (:require [immutant-hystrix-stream.stream :as hs])
    (:require [com.netflix.hystrix.core :refer [defcommand]])
    (:require [immutant.web :as web]
              [immutant.scheduling :as sch]))

(defcommand my-job
 []
 (do-stuff-that-might-fail))

(defn -main
 [& args]
 (sch/schedule my-job :every [1 :second])
 (web/run hs/hystrix-stream :host "localhost" :port 8082 :path "/hystrix-stream"))

Overview

This library serves a very specific purpose, so if you aren't using Immutant and Hystrix together it probably doesn't do you any good.

If you are, however, this will let you create a stream of Hystrix metrics (presumably from your Hystrix-clj commands) for consumption by the Hystrix Dashboard. See the example application for a quick usage overview.
