Riemannの特定の日時や特定の時刻に電子メールアラートを設定することはできますか？

Question

私はプロジェクトでRiemannを使用して電子メールアラートをトリガーしています。特定の日のみの電子メールアラートをトリガーすることは可能ですか（月曜の午前3時から午後8時まで）。

もしそうなら誰でも参考に手伝ってください。

私の更新されたコード：

(tcp-server {:host "127.0.0.1" :port 5555}) 

(let [userindex1 (default :ttl 300 (update-index (index)))]) 
    (let [email (mailer {....email configuration})] 
      (streams 
     (where (service "log") 
      (smap 
       (fn [events] 
       (let [count-of-transaction (count (filter #(= "error" (:type %)) events))] 
        (event 
        { 
        :status "Failure" 
        :metric count-of-failures 
        :total-fail (< count-of-failures 2)}))) 

       (where (let [now (clj-time.core/now)] 
        (and (<= 3 (clj-time.core/hour now) 20) 
         (<= 1 (clj-time.core/day-of-week now) 5) 
         (= (:status event) "Failure") 
         (:total-fail event))) 
       (rollup 1 200 
       (email "xxx@xx.com") 
       ))prn))))

し、実行：あなたはここでwhere句の条件付き位置決幅の中に「警告」を送信するタイミングを決定する曜日と時間に依存例の設定ですが、あなたが望む任意のコードを置くことができますテスト：私はリーマンでのユニットテストでは、固定時間窓を機能させるために方法を見つけ出すことができなかったので、私はfixed-event-windowを使用この例では

root@176ee53d0c62:/test# riemann test sample.config

Testing riemann.config-test 
emailing about {:service log, :type error, :time 42, :status Failure, :metric 3, :ttl 300, :total-fail true} 

Ran 1 tests containing 2 assertions. 
0 failures, 0 errors. 

。これまでに解決策を見ることに興味があると思っていたことを理解するのに十分な時間がかかったと思います。固定時間ウィンドウに変更すると、テストは実行されないことを除いて、同じ動作をします。
