Prometheus Ruby Clientの実行方法

Question

Prometheus Ruby Clientを実行し、統計値を収集してPrometheusデータベースに保存したいと考えています。

私はここでの指示に従ってきた：私は2つの宝石、prometheusとprometheus-clientをインストールした https://github.com/prometheus/client_ruby#rack-middleware

ラックミドルウェア。

exporter.rb（https://github.com/prometheus/client_ruby/blob/master/lib/prometheus/middleware/exporter.rb）とcollector.rb（https://github.com/prometheus/client_ruby/blob/master/lib/prometheus/middleware/collector.rb）の場所に保存されます。私は地元でconfig.ru（https://github.com/prometheus/client_ruby#rack-middleware）を保存したprometheus/middleware

フォルダ。

その後、私は、ラックのWebサーバーを開始しました：rackup -d config.ru -I /home/sven/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/prometheus-client-0.6.0/lib -I /home/sven/.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/quantile-0.2.0/lib

-Iは、ステートメントが必要なファイルをご覧いただくことが必要である含まれています。

は、その後、私はこのエラーを得た：

Answer 1

あなたがPrometheus::Middleware一方client_ruby 0.6.0を使用していることだけclient_ruby 0.7.0のために利用可能であるようです。

チェックhttps://github.com/prometheus/client_ruby/tree/v0.6.0

Answer 2

この問題は、あまりにもトリッキーだった、と私はInfluxDBに切り替えることにしました。 そして数分でRuby Clientを実行できました。プロメテウスよりはるかに優れているようです。ごめんなさい。
